... to create a new direction for shearing and compression. The Urica fault and the folds and thrusts of the Bergantin block closely follow the application of the strain ellipsoid for deformation. Further analysis of the stress and strain found in northeastern Venezuela strongly suggests that the Anaco fault...

.... Samples of the Vidoño shale were collected in various outcrops in the Barcelona-Puerto la Cruz and Bergantin regions of Anzoategui, Venezuela, during the summer of 1957. Particular attention was paid to a 142-foot exposure of black shales and calcareous siltstones (known as the Alcabala section...

...Hollis D. Hedberg; Augustin Pyre ABSTRACT A reference section for the 40,000 feet of Cretaceous and Tertiary sediments of northeastern Anzoátegui (Venezuela) was established several years ago on Rio Querecual and in the vicinity of the town of Santa Inés. Subsequent studies on the west and east...

...H. D. Borger ABSTRACT Venezuela ranks second only to the United States in oil production, and the Quiriquire field has contributed 6 per cent of Venezuela’s total output. Early discovery of the oil and gas seeps (at the turn of the century) on the northern edge of the tectonically unstable Maturín...

... (Luna-Cogollo limestone, Cantil-Guayuta formation, Bergantin-Querecual beds) and an upper division of shales, marls, and a few sandy and calcareous intercalations (Colon shales, Guayuta group, San Antonio formation). 1 Manuscript received, March 8, 1939. 2 The Caribbean Petroleum...

... within R. A. Liddle’s comprehensive work on Venezuela, little or nothing has been published on the geology of Anzoategui. This paucity of data is not due to lack of exploration, since more than one generation of geologists has made field studies of selected areas in the state. These studies have been...

...Emile Rod; Wolf Maync ABSTRACT The understanding of the Cretaceous stratigraphy in Venezuela is hampered by some vaguely defined or unsuitable type localities. A revision of the Cogollo formation of Western Venezuela is proposed as fresh exposures at the type locality on the Río Cogollo revealed...

... Cogollo section including all three formations can be observed. Garner’s Middle Cretaceous Cachirí limestone should not be confused with Liddle’s Devonian Río Cachirí group previously mentioned in this paper. The combined El Cantil, Chimana, and Bergantin formations of eastern Venezuela...
