Palynology and
ichnology in the determination of Cretaceous -Tertiary unconformity contact in
southwestern Venezuela and their impact in hydrocarbons exploration. The material
comes from two wells drilled at the Barinas State. Integration of results is
due to analyses of marine and terrestrial palynomorphs, and ichnofacie that
allows to determine the Maastrichtian - Middle Eocene unconformity at well #1
at a deep of 9,901´5´´ by the presence of Foveotriletes margaritae (Van
der Hammen) Germeraad, Hopping & Muller, peridinioid dinocysts and the Glossifungites
ichnofacies. At well # 2, the unconformity was established by the presence
of Foveotriletes. margaritae, Ariadnaesporites Potonie and Buttinia
andreevi Boltenhagen at a deep of 10,154´6´´.
