laguna salada baja california

Baja California Mexicali, Baja California es un destino de contrastes que siempre sorprende a quienes se atreven a explorarlo, una muestra de ello es Laguna Salada. Several faults cut the west margin of the floodplain lagoon and the hanging wall of both the Cañada David detachment and the Laguna Salada fault. This contrasts with the ∼35–42 km crustal thickness beneath the peninsular ranges (e.g., Sierra Juárez) (Lewis et al., 2001). The navy-blue lines are the modern flooding channel within LSB and the Hardy River east of Sierra El Mayor. However, the low resolution and low number of seismic lines prevent a detailed interpretation and correlation of most sequence boundaries. It is also notorious for its dust storms (when dry), usual… Discover the beauty hidden in the maps. The rupture propagated north along a complex dextral-oblique fault zone parallel to Laguna Salada fault through the Sierra Cucapah (Fletcher et al., 2014; Terán et al., 2015). My original plan was to explore Laguna Salada by driving on the dry lake bed (playa) surface — but it did not turn out to be dry. 4B). 1), and only two major earthquakes have been previously located within the eastern basin margin—the 1892, Mw > 7, and the 1934, Mw 6.5 (Ellsworth, 1990) (Fig. International Human Resources Development Corp. Generalized geologic map of the Laguna Salada Basin (LSB) (modified from Fletcher and Spelz, 2009). It is shaped somewhat like an hour-glass, long and skinny and very narrow at the center. It is in the state of Baja California in the city of Mexicali. Industry seismic data collected by Petróleos Mexicanos (PEMEX) during the early 1980s and three exploratory wells drilled by CFE provide a unique opportunity to further investigate the structure and stratigraphy of LSB, particularly the geometry of an active detachment fault in depth (Axen et al., 1999; Fletcher and Spelz, 2009). Below are listed direct links for hotels in major cities and popular locations in Laguna Salada. pesq. The Laguna Salada Basin is an active asymmetric depression structurally controlled by the Laguna Salada fault and the Cañada David detachment fault. Basin-wide continuous seismic reflections of facies 1 distinctively represent stratigraphic sequence boundaries in the LSB. The late Neogene sedimentary sequence overlies in fault contact Paleozoic and Mesozoic metamorphic and granitic intrusives that form the footwall block of the Cañada David detachment (Siem and Gastil, 1994). The seismic source for the acquisition of the seismic data was dynamite. Abbreviations: LSF—Laguna Salada fault; CRF—Cañón Rojo fault; CHF—Chupamirtos fault; CDD—Cañada David detachment; SJFZ—Sierra Juárez fault zone, Indiviso fault (from Fletcher et al., 2014); MGE—main gulf escarpment; Pac—Pacific plate, NAM—North American plate; ELS1, ELS2, and ELS3 are exploration wells by Comisión Federal de Electricidad. The lower unit is early Pliocene silty-clayey yellow-green marine mudstone (Siem and Gastil, 1994; Vázquez-Hernández et al., 1996). Two-dimensional (2D) modeling of gravity data (García-Abdeslem et al., 2001; Martín-Atienza 2001; Cortés-Arroyo, 2011) and stratigraphic studies in the Cerro Colorado basin and in three exploratory wells of Comisión Federal de Electricidad (CFE) (Vázquez-Hernández et al., 1996; Dorsey and Martín-Barajas, 1999; Martín-Barajas et al., 2001) are consistent with a northwest-trending, strongly asymmetric depocenter with a maximum sedimentary fill of ∼3 km adjacent to the Laguna Salada fault in the northwest (Fig. Intervals of low to medium amplitude laterally wedge out westward and interfinger with chaotic reflectors of facies 4. These yellow lines (faults) roughly follow the west shoreline of the lake. Facies 1 and 2 are high-amplitude, laterally continuous reflectors that represent flooding and prolonged lacustrine conditions. 1 and 2). The two seismic images of the supradetachment basin domain capture the hanging-wall basement ramp that subsided ∼2.7 km below sea level, whereas the detachment fault has accumulated a minimum of ∼10 km of finite extension. Clusters of microseismicity located in the south escarpment of Sierra Juárez and Laguna Salada are likely related to the Sierra Juárez fault zone. [4]​[3]​ Desde finales de los ochenta a la fecha, el vaso de la laguna se encuentra predominantemente seco, a excepción de un corto periodo entre 1997 y 1999. In seismic lines 4973 and 4965 (Fig. The EMC earthquake had little influence in the subsidence of LSB but revealed the existence of a previously unidentified fault system in the southwest part of the delta of the Colorado River, west of the Cerro Prieto fault, which was considered the main plate boundary (Figs. ELS-1 to ELS-3 are the exploration wells drilled by the Comisión Federal de Electricidad (CFE). This estimation indicates that the subsurface portion of the Cañada David detachment accommodates 24% of extension in the western main plate boundary zone. (A) Profile 5076-a (see inset map for location) along the south basin domain. 4 and 6). (2001) interpreted a strong positive gradient of the Bouguer gravimetric anomaly along the eastern margin as related to a major structural boundary of crustal rocks with density contrasts caused by the dextral oblique Laguna Salada fault and the Chupamirtos dextral oblique fault (Fig. 6A and 6B) indicate deepening of acoustic basement toward the east; from ∼250 m to more than 1200 m in profile 4949, and to >1600 m at the eastern end of profile 4957. Baja California. Both control the modern depocenter and subsidence in the northern half of the basin. 2). El 1 de agosto de 2012 tuvo lugar el primer lanzamiento en el estado de Baja California de un cohete, fabricado por alumnos de la carrera de ingeniería aerospacial del centro de ingeniería y tecnología de la UABC.

Structural map of the Laguna Salada Basin (LSB) and surrounding areas. The CDD and Laguna Salada faults are, thus, a common example of coexistence of two fundamental modes of deformation and strain partition in the northern Gulf of California rift. oscar baylon grecco. Interestingly, the two lower sequences are wedge shaped with a maximum thickness adjacent to the fault plane (Figs. [6]​ Al evento asistieron alrededor de 40 000 personas con boleto pagado[7]​ y alguna fuente afirma que el número superó los 50,000 espectadores. La Laguna Salada recibe una precipitación anual promedio de 67.6 milímetros. The acoustic basement has a prominent vertical offset in the southern part of profile 5076-b (Fig. We first present the principal structural and stratigraphic characteristics to gain insight about the architecture and the amount of subsidence and extension principally in the southern LSB. La Laguna Salada ha sido, en varias ocasiones, escenario de eventos culturales de índoles diversas, en especial a partir del inicio del siglo XXI, por citar los más destacados: fue marco de un evento denominado: Pavarotti sin fronteras. Maphill is more than just a map gallery. The vertical component (e.g., subsidence) of this geometric analysis is of ∼2.8 km. La película: Resident Evil: extinción, usó la Laguna Salada como locación fílmica[9]​ de alguna de sus escenas, durante el mes de mayo del 2006 y uno de los episodios del programa: Curiosity,[1] presentado por Discovery Channel, empleó el vaso seco de la laguna para experimentar y filmar la caída de un avión Boeing 727,[10]​ este fue el segundo experimento de su tipo realizado en el mundo y fue realizado el 27 de abril de 2012,[2] para proyectarse en televisión el 7 de octubre de ese mismo año en los Estados Unidos.[11]​. TYPE OF FAULTING: right-lateral strike-slip. Above ∼400 m, the poor resolution prevents further seismic interpretation, and the activity of faults located farther east in the sedimentary wedge is not imaged (cf. 6A). Baja California Laguna Salada La Laguna Salada es una depresión arenosa que comienza en la inmediación suroeste del cerro El Centinela y se extiende hacia el sur por entre la sierra Cucapá y la sierra de Juárez , dentro del municipio de Mexicali, B. C. , México . La extensión de las aguas durante aquellos años fue variable; en algún momento llegó a tener 60 km de largo por 17 km de ancho y de entre 20 cm hasta 4 metros de profundidad, tal volumen dio pie a actividades pesqueras y turísticas. The water of the Sea of Cortés, which once filled this area, evaporated in the mid-eighties leaving a rough terrain of 60 kilometers (37 … Geosphere 2016;; 12 (4): 1283–1299. 3). Above ∼1000 m deep, seismic facies of type 4 predominate, as well as in most of the south part of this profile (Fig. Overall, the lower unit in the Cerro Colorado basin has similar lithological and chronostratigraphic characteristics to units of the Imperial Group in the southwestern Salton Trough (Winker and Kidwell, 1996; Dorsey et al., 2011). The Laguna Salada Basin in northeastern Baja California, México, is an active half-graben with subsidence principally controlled by two major faults along the eastern basin margin—the Cañada David detachment fault and the dextral oblique Laguna Salada fault. Southward, the Cañón Rojo fault likely loses vertical displacement because it transfers part of the slip into the Chupamirtos fault. Seismotectonic map of northern Baja California, Mexico, and southern California, USA. Processing and interpretation of the seismic data make use of the ProMax anpd SeisWorks software of Landmark™ and OpendTectTM. The historical seismicity in the LSB is low in the NW sector (Fig. Guadalupe Canyon Oasis is located southwest of the city of Mexicali in Northern Baja California, Mexico. La Laguna Salada tiene un clima seco desértico, y al ser una zona debajo del nivel del mar, las temperaturas pueden llegar a superar los 50°C. This intersection represents the minimum amount of subsidence in LSB controlled by the detachment fault. 4), and they do not offset a thick interval of high-amplitude continuous reflectors observed at ∼600 m deep. The processing and interpretation of five seismic profiles indicate that these two master faults define two distinctive basin domains. 5A). Upward sandy deltaic deposits progressively alternate with locally derived, coarse-grained sandstone and conglomerate from local source alluvial fans from Sierra Juárez and Sierra Cucapah and El Mayor. The inset map shows the major tectonic features of northwestern Mexico and the location of the study area (i.e., the Laguna Salada Basin—LSB). Foto: Cortesía Secretaría Turismo Baja California. 6). A distinctive feature in the two seismic images of the CDD at depth is the eastward shift of the depocenter through time. ing. It is possible that detachment faults initiated during the early phase of transtension and produced a broader supradetachment depocenter that was subsequently overprinted by the Laguna Salada fault. Historical seismicity (Ellsworth, 1990; Doser, 1994; García-Abdeslem et al., 2001; Hough and Elliot, 2004) and paleoseismological studies (Mueller and Rockwell, 1991, 1995; Fletcher and Spelz, 2009; Fletcher et al., 2014) demonstrate that LSB is controlled by the active LSF and the Cañada David detachment fault. There, a major fault produces a vertical offset of more than 500 m along a horizontal distance of ∼2 km (cdp ∼6550–6750). En la actualidad esta región es la zona más baja de todo el país con una altitud de 12 metros bajo el nivel medio del mar.[2]​. 4B), we interpret five stratigraphic sequences with basal boundaries defined by these continuous reflectors of facies 1. 4A and 4B). During the Pliocene, uplifting of the mountain ranges of Sierra Cucapah up to 700 m progressively isolated Laguna Salada from the delta plain and from the southwestern Salton depression (Axen et al., 2000; Martín-Barajas et al., 2001) (Figs. The minimum depth to depocenter in the northern domain of the Laguna Salada Basin is well ELS-1, which drilled ∼2.4 km of deltaic, lacustrine-estuarine and alluvial fan sedimentary deposits (Martín-Barajas et al., 2001). However, this isn’t exactly a typical lagoon. In profile C, the projection of acoustic basement to intersect the Laguna Salada fault yields a depth to basement of ∼3800 m assuming the fault dips 70° west. The CDD likely includes synthetic and antithetic faults that merge at depth into the master fault. In summary, the basin fill is predominantly composed of marine to deltaic fine-grained sediments funneled by the Colorado River into the northern Gulf of California and delta plain. On the basis of Quaternary fault scarp along the Laguna Salada fault and gravimetric and magnetic surveys of Kelm (1972), Mueller and Rockwell (1991) interpreted LSB as a “pull-apart” basin controlled by the NW-oriented, dextral-oblique Laguna Salada fault. 5B) contains a west-dipping fault that produces ∼500 m vertical offset of the acoustic basement in the hanging wall of the CDD. Located just south of the border, in the Sonoran desert of Baja California near Mexicali. The Laguna Salada Basin (LSB) in northeastern Baja California, México, is an ∼20-km-wide, ∼100-km-long tectonic depression at the northwestern side conterminous with the Gulf of California rift system (Fig. Low-angle normal faults and seismicity: A review: Stratigraphy of a marine rift basin: Neogene of the western Salton Trough, California, Field Conference Guidebook and Volume for the Annual Convention, San Diego, California, May, 1996, Pacific Section, American Association of Petroleum Geologists, This site uses cookies. 1 and 2). The Cañón Rojo fault accumulates more than 2 km of subsidence, but geometric considerations indicate that the basement in the hanging wall of the Laguna Salada fault projects to a depth of ∼3.8 km and intersects the 70° west-dipping Laguna Salada fault. Subsequently, the data were interpreted using the technique of Badley (1985). Get free map for your website. For Sale: 160000 - Residential, 3 bed, 2 bath, 1,453.14 sqft at Laguna Salada, Los Santos in Tijuana. We interpret that these faults are a clear expression of several synthetic and antithetic faults cutting the hanging wall of the detachment and probably accommodating significant amounts of basin subsidence. The correlation of the Cañón Rojo fault and the largest fault in profile 5076-b (Fig. 4). Due to their lateral continuity, facies 1 and 2 are interpreted to represent flooding and prolonged lacustrine conditions produced by the Colorado River entering Laguna Salada Basin. The lower lens shape sequence is ∼4 km wide and ∼500 m thick, and the seismic reflections are parallel to the acoustic basement (Fig. Neogene structural evolution of the Sierra San Felipe, Baja California: Evidence for proto-gulf transtension in the Gulf Extensional Province? The south part of longitudinal profile 5076-b (Fig. Difícilmente una persona se imaginaría un páramo, un lugar seco y desértico donde prácticamente no hay ninguna señal de vida. Seismic facies 1 and 2 predominate in the east and central portions of seismic profiles where the depocenter accumulates thick, fine-grained sedimentary sequences. Southward the modern basin becomes narrower and connects through a ∼5–10-km-wide inlet with the modern delta plain of the Colorado River and the tidal flats of northern Gulf of California (Fig. We are located just 50 miles southwest of Mexicali and 135 miles southeast of Tijuana, off Highway 2. This suggests either a basin depocenter above homogeneous lithology of crustal rocks or a deep crustal root that flexurally supports topography (García-Abdeslem et al., 2001). This implies that pre-rift Miocene volcanic rocks may be present in depth within the LSB. 5A) and likely maintains a similar depth as in line 5076-a (Fig. This depocenter broadens upwards and probably represents a broader zone of subsidence and/or an increase in sediment supply. The Laguna Salada fault (LSF) and the low-angle Cañada David detachment fault (CDD) control the basin architecture and subsidence and represent two distinct basin domains (Siem and Gastil, 1994; Axen, 1995; Mueller and Rockwell, 1995; Axen et al., 1999; Spelz et al., 2010).

The low-amplitude wavy reflectors of seismic facies 3 are commonly observed above facies F1 to lateral interfingering on intervals of facies F2 and F1. 2) forming a releasing stepover. We then discuss the distribution of seismic facies as related to distinct depositional environments within the basin. Hotels in Laguna Salada. The acoustic basement underlies the white unit at ∼1600 m as defined in well ELS-2 (Fig. The 2.8 km of basin fill observed in seismic profile 4965 represents a minimum subsidence rate of ∼0.4 mm/yr. enrique aranda j. i n d i c e. 1. caracteristicas de la laguna salada. The minimum displacement along the fault plane is ∼10.1 km, and the minimum horizontal displacement is ∼9.7 km. The contrast in structural style and the amount of subsidence among the north basin domain controlled by the dextral oblique Laguna Salada fault and the south basin domain controlled by the CDD fault requires a structural boundary likely in the Chupamirtos fault (Mueller and Rockwell, 1991). Seismic facies 2 is high- to low-amplitude, laterally discontinuous reflectors also representing flooding conditions. Another prominent relief in the acoustic basement occurs at the northwest end of profile 5076-b (Fig. Climatic forcing and changes in sea level likely control the shift from estuarine conditions (flooding) to hyper-arid playa lake conditions (e.g., sea level lowstand) in Laguna Salada (Contreras et al., 2005). Up to ∼700 m of Late Pliocene to present lacustrine-estuarine deposits interfingered by progradational and retrogradational alluvial wedges represent the modern structural and sedimentary setting in LSB (Figs. This geometric projection suggests that basement in the hanging wall intersects the Laguna Salada fault at ∼3.8 km below the surface, assuming that the Laguna Salada fault maintains a ∼70° dip to the west (Fig. An independent estimate of depth to basement is the eastward projection of acoustic basement in profile 4957. The modern lake basin is bordered by a 5–15-km-wide belt of coalescing alluvial fans derived from Sierra Juárez in the west and by a narrower 0.5–3-km-wide belt of alluvial fans fed from the Sierra Cucapah and Sierra El Mayor in the east. As the detachment fault becomes low angle, the horizontal component increases and displaces the depocenter basinward as proposed by Fletcher and Spelz (2009). For these estimates, we infer that the acoustic basement is a flat ramp that deepens at an angle of ∼20° similar to average basement dip in profile 4957 (Fig. These conditions might be similar to the modern situation in LSB produced by damming the Colorado River since the early part of the twentieth century. El sendero se usa principalmente para hacer senderismo. Its location projects south of the Cañón Rojo fault, and we speculate these two faults may correlate. 22860, México. In the present study, we have processed and interpreted multichannel two-dimensional (2D) seismic-reflection data collected by PEMEX in Laguna Salada Basin from the “Delta del Colorado” prospect. High-amplitude continuous to discontinuous reflectors (facies 1 and 2) above basement alternate at intervals tens to a few hundred meters thick. This unit also includes metric to sub-metric evaporite deposits and locally derived conglomerate and breccia. 1). The stratigraphy in ELS wells provided stratigraphic and seismic velocity constraints (Álvarez-Rosales and González-López, 1995; Martín-Barajas et al., 2001). Abbreviations: Laguna Salada fault—LSF; Borrego fault—BF; Cañón Rojo fault—CRF; Pescadores fault—PF; Chupamirtos fault—CHF; Monte Blanco detachment—MBD; Central Mayor fault—CMF; red bars where the displacement was greater than 0.5 m (Fletcher et al., 2014); Comisión Federal de Electricidad exploratory well—ELS-1 to ELS-3. The lower sedimentary unit reported in Laguna Salada is the Imperial mudstone unit, which may correlate to either the Latrania Formation dated 5.2–6.1 Ma or to the lower part of Deguyinos Formation (5.1–4.2 Ma) (Dorsey et al., 2011) based on similar distinctive lithology and paleodepths (Vázquez-Hernández et al., 1996). The Cañon Rojo fault is responsible for the abandonment of the northern synformal megamullion of the CDD and defines the position of the modern range front (Mueller and Rockwell, 1995; Dorsey and Martín-Barajas, 1999; Fletcher and Spelz, 2009). Below 1300 m, a ∼200-m-thick interval of low-amplitude reflectors named here the “white unit,” overlies chaotic reflectors that we interpret as the basal conglomerate unit and granitic basement reported in well ELS-2 (see Fig. 5A), but the seismic image lacks the resolution to interpret any fault that may control this basement relief. 4 and 6). Southeast, this earthquake and its aftershocks ruptured previously unidentified faults in the delta plain south of the epicenter and evidenced a wider plate boundary zone at this latitude (Hauksson et al., 2011; Chanes-Martínez et al., 2014). The largest SW-dipping fault to the right of the seismic section is the Cañada David detachment (CDD). 2). The most obvious faults are observed in profile 4973 to form a ∼2-km-wide sag in the acoustic basement (Fig. For both (A) and (B), yellow line is the acoustic basement. During lowstand sea level, Laguna Salada is intermittently dry, and playa-lake deposits must enhance progradation of alluvial fan and eolian deposits into the basin floor. Otro escenario sin igual se encuentra en Laguna Salada , un verdadero oasis entre las montañas. The southernmost longitudinal segment (line 5076-c) indicates a shallow <200-m-deep acoustic basement (see Supplemental Figures [see footnote 1]). The first survey, which was carried out in 1991, was with five seismic stations located in the northern part of the basin recording from July 8 to December 17. By continuing to use our website, you are agreeing to our, Álvarez-Rosales and González-López, 1995, GEOLOGICAL EVOLUTION OF THE LAGUNA SALADA BASIN, Copyright © 2021 Geological Society of America. 6A) matches the depth to crystalline basement of well ELS-2 and supports this interpretation. 8). ... Laguna Salada. We interpret facies 4 as high-energy, alluvial-fan coarse-grained deposits prograding over the basin floor from the west in the range front of Sierra Juarez. 4B and 7). We want to thank Consejo Nacional de Ciencia y Tecnología (the National Council of Science and Technology [CONACYT]), México, for financial support, to PEMEX Exploration and Production for allowing the use of seismic data and Halliburton/Landmark, OpendTect, and Google Earth Pro for the use of their software through the University Grant Program to Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE). 9). 10.5 Ma volcanic deposits across the southern range front of Sierra Juárez (Mendoza-Borunda et al., 1998). The most important result is the direct evidence of the Cañada David detachment fault beneath a 2–2.5-km-thick sedimentary wedge in the south domain of LSB. The north domain is controlled by the high-angle, dextral oblique Laguna Salada fault and the high-angle, dip-slip Cañón Rojo fault. 4), facies 4 is progradational eastward and is absent or poorly expressed in the eastern side of transversal profiles, where facies 1 and 2 dominate. We interpret that facies 4 is produced by anastomosing channels and bars of alluvial fan deposits from Sierra Juárez (Figs. estudio preliminar de la pesqueria de la laguna salada, baja california. Uncertainty remains regarding the epicentral location and the magnitude of the earthquake that occurred February 23, 1892, because its location was calculated based on the intensity distribution in southern California (Strand, 1980). Esta página se editó por última vez el 23 nov 2020 a las 18:35. The Laguna Salada fault is high angle (∼60° to 70°) and forms a releasing stepover in the Cañón Rojo fault (Fig. However, interpretation of seismic sequences and facies distribution is limited due to low resolution and low number of seismic lines and is beyond the scope of this paper. We thank Sergio Arregui for technical support, Martín Pacheco and Ramón Mendoza-Borunda for fruitful discussion on interpretation. 5B).

In both 4965 and 4973 profiles, the upper sedimentary sequences have a broader distribution and uniform thickness across the basin, although slightly thicker to the east. This sag is likely controlled by a west-dipping fault and at least two east-dipping antithetic faults. The north domain is a dilatational stepover (or pull apart) controlled by the northwest-trending, west-dipping, dextral-oblique Laguna Salada fault and the north-trending, dip-slip Cañón Rojo fault, which defines the south boundary of the pull-apart basin domain. 5B) shows nearly 11 km of chaotic reflectors (facies F4) that we also interpret as alluvial fan deposits close to the north end of Sierra Las Tinajas (Fig. Geologic cross section derived from the seismic profile 4965 (Fig. Laguna Salada on Map What Makes the Laguna Salada So Interesting? 3).
