“…fl ow of sediment, coming from the shelf. Even without any correction for tectonic rotations of crustal blocks, in general, the directions found are consistent with the proposed paleogeography of the eastern and western margin of northern South America (Villamil, 1998;Villamil et al, 1999;Erlich et al, 1999b). Thus, during the Cenomanian to early Maastrichtian, turbidity and gravitydriven fl ow occurred.…”

“…It is important to recognize how the clastic sedimentation in the Albian is recorded in western and eastern Venezuela. Are the sediments related to a major geotectonic feature in the Proto-Caribbean crust, or are they related to a long-term climatic change before the worldwide Late Cretaceous transgression (Yoris, 1984(Yoris, , 1992aPindell and Tabbutt, 1995;Pindell et al, 1998;Villamil, 1998;Erlich et al, 1999a)?…”

“…The upper member of the Capacho is the Guayacán Member, a thick carbonate deposited in a shallow marine environment underlying the La Luna-Navay Formations. Maximum anoxia may have occurred during the Turonian to the Santonian (Erlich, 1999;Erlich et al, 1999aErlich et al, , 1999b. Recent chemostratigraphic studies (V, Ni, Mo, Zn, and total organic carbon; Mata, 2001) identifi ed a maximum anoxia peak in sections located in Táchira State.…”

“…Ford and Houbolt (1963) included the basal glauconitic limestone of the Socuy Member in its type section (Socuy spe394-02 page 65 river, Perijá Mountains) in the Tres Esquinas Member of the La Luna Formation. The basal age for the Socuy Member is Campanian (González de Juana et al, 1980;Erlich et al, 1999b), and the basal age for the Tres Esquinas Member is late Santonian (Erlich et al, 1999a(Erlich et al, , 1999b. On the southern fl ank of the Andes, the upper part of the source rocks becomes transitional with the Colón and Mito Juan.…”

Knowledge of the geologic evolution of the northern margin of South America has increased tremendously, inspired by the occurrence of huge hydrocarbon deposits. This margin originated in late Triassic time when the supercontinent of Pangea broke up and North and South America drifted apart. The passive margin accommodated a thick sequence of Jurassic to Tertiary sediments. During the latest Cretaceous to the Present, the Antilles volcanic arc, built upon the Caribbean plate, migrated southeastward and collided obliquely with South America. This collision resulted in the diachronous accretion of allochthonous terranes as well as diachronous formation of a fold and thrust belt. This belt was initiated in the west (Colombia) during the latest Cretaceous and progressively moved east and reached Trinidad only in Miocene time. In front of this thrust belt, diachronous foreland basins developed. The present paper reviews the geologic evolution of northern Venezuela and adjacent areas in the Caribbean Sea, based to a large extent on a huge amount of new data released by oil companies and data collected by universities.

“…During the Cretaceous passive margin phase (1 in Fig. 16) the subsidence was mainly related to post-rift cooling processes; the available accommodation space was also associated with eustatic changes (Erlich et al, 1999).…”
