It provides a background to the field excursions which will follow the technical sessions. Trinidad lies on the mobile northern side of the eastern Venezuela basin and was characterized, by intermittent tectonic activity which interrupted and modified the sedimentation. As a result, several local facies were developed which have no direct counterparts in eastern Venezuela.enGeologyTechnical Report
