... by a nearby fault of the main gulf escarpment such as the Loreto or Escondido fault. Based on the observed effects of the A.D. 1810 and 1878 earthquakes, Loreto has a significant seismic ground‐shaking hazard and is highly vulnerable to amplification of seismic ground shaking and related fissuring and soil...

... granite, Mc—Miocene Comondú Group, Ps—Pliocene sedimentary strata. Thin dashed lines represent bedding. The tilt of individual fault blocks is well defined by surface geology or simple projections, except for the block east of the Escondido fault, which is not well defined and may tilt to the east...

... work was done, subsurface study shows that Elaine field is the largest of these plugs. Seismic studies also show that the Austin Chalk, on whose surface the lava was extruded, is highly fractured and faulted. The Austin under the Elaine field is the lowest structural feature in the area. The Anacacho...

... the Puerto Angel transect than to the west, at Puerto Escondido, where it is 100 km wide ( Campa and Coney, 1983 ). The narrowness of the Xolapa Complex at Puerto Angel compared to Puerto Escondido may be explained by the presence of a major fault orthogonal to the strike of the Xolapa Complex between Puerto...

... in the light of his present knowledge in making a definite statement concerning the Escondido-Pappagallos contact, but it appears likely that the contact may approximately follow in this vicinity the Rio Salado. Dumble 2 states that Wilcox and Carrizo beds occur near the mouth of the Arroyo Reparo...

... stratigraphic architecture and interprets depositional processes of outcropping deep-water upper-slope and deltaic strata of the Tres Pasos and Dorotea formations of the Late Cretaceous Magallanes foreland basin, southern Chile. The Dorotea delta system at Cerro Escondido is the topset element of an unstable...

... relations to formations below and above it are stated. The Eagle Ford clay, the Austin chalk and its equivalents, the Taylor marl and its equivalents, and the Navarro and Escondido formations and their equivalents are successively treated in a similar way. Character .—The Woodbine sand, the oldest...

..., it was either collected: (1) “south of Puerto Escondido” (p. 1020), i.e., in the sea; (2) “∼7 km north of the Pacific Coast at Puerto Escondido” (p. 1021); or, using the coordinates presented in their Table 1, (3) in the Xolapa terrane, but just south of the Juchatengo terrane ( Grajales-Nishimura et al., 1999...

.... For example, phreatomagmatic volcanoes are common in basin or coastal areas as well as in fault zones and other fracture systems that host groundwater ( Lesti et al . 2008 ), whereas spatter cones and lava flows occur in topographically higher locations ( White 1991 ; Sohn & Park 2005 ). One of the main...

... Escondido rhyolite and granite of 519 ± 4 Ma and 521 ± 4 Ma, respectively. These three crystallization ages also indicate that ductile dextral shearing and mylonitization associated with the Pampean D 2 event terminated in the Early Cambrian. Both stages of Pampean deformation in this segment of the western...

..., Camalotito, and Las Ollas, the latter being undoubtedly the best exposure recognized at present. LOC is in fault contact and overlain by the Zihuatanejo volcanics, but it is more commonly surrounded by granitic intrusions. Figure  2 shows schematic structural sections of Puerto Escondido and Las Ollas areas...

..., Vicksburg, and Frio where hydrocarbon traps typically are fault controlled. Stratigraphic traps include porosity pinchouts and deltaic-distributary systems within the trends. Fig. 1 —Developments in South Texas, 1974. Fig. 2 —South Texas wildcat activity, 1974. In 1974 2,282 wells...

... domains of the eastern boundary zone. Red triangles are the global positioning system (GPS) sites of this study. Ca—Carmen Island; Ce—Cerralvo Island; Cf—Carrizal fault; Ecf—Escondido fault; ES—Espiritu Santo Island; ESf—Espiritu Santo fault; Gf—La Gata fault; Lf—Loreto fault; SCf—San Jose del Cabo fault...
