The Cordillera of eastern Venezuela is a south-vergent fold-thrust belt of Neogene age formed on the South American plate and its Atlantic passive margin series by right-lateral transpression during the relative eastward migration of the Caribbean plate. Together with the topographically high Serranía del Interior, the Maturín subbasin is the easternmost onshore segment of the Venezuelan Cordillera, its foothills, and its foreland. Oilfields and data coverage of the Maturín subbasin abundantly document the compound sediment wedge, its structure, and its sedimentary and tectonic evolution.
In the Monagas foothills, décollements at the base of the Miocene are responsible for the formation...
