Geological structure of Binh Long - Ta Thiet area and tectonic evolution of Pre-Cenozoic sedimentary basins in the Southeast region of Vietnam

Abstract

The Binh Long - Ta Thiet area is one of the studied areas of the Petrovietnam University’s project entitled “Survey and selection of the routes for field study in structural geology and geotectonics in Binh Phuoc and Dong Nai provinces and the coastal region between Mui Ne and Vung Tau” in 2016. On the basis of integration and analysis of available research reports and geological mapping, combined with additional field surveys, the authors have more accurately delineated the boundaries of geological formations in the studied area and the structural horizons that reflect the local folding and faulting features of extensional basins formed by the Late Permian – Triassic collision. They also contributed to the interpretation of the tectonic development history of Pre-Cenozoic sedimentary basins in the Southeast region. Researches can be conducted to assess the oil and gas potential of these basins.
