Tertiary Stratigraphy and Sedimentary Environments of the Oil Bearing Sands of the Orinoco Oil Belt, Venezuela, South America
The stratigraphic column of the Orinoco Oil Belt (OOB) comprises rocks from Precambrian up to Recent. The main oil bearing sands form part of an Oligocene- Miocene sedimentary wedge onlapping the Guayana Shield to the south. Structural interpretation along with lithostratigraphic correlation, core studies (sedimentology and bioestratigraphy), and seismic stratigraphic analysis, permitted the recognition of at least two main provinces, separated by a tensional faulted system. The eastemly province presents the tertiary rocks as transgressive sediments overlying the Precambrian basement. In the westemly province, the tertiary sediments unconformably overly the Cretaceous and Palaeozoic rocks, which are filling incised valleys.
