Crustal structure and margin configuration of the La Baja Guajira basin, Colombia: regional 2D seismic reflection interpretation, gravimetric and thermal modelling

Leidy Castro-Vera , Ralf Littke , Stefan Back & Rocío Bernal-Olaya
The La Baja Guajira Basin (LBGB) is the primary gas-producing region of Colombia and represents South America's northernmost prolongation. This study presents an analysis of regional 2D-seismic reflection data of LBGB integrated with borehole and gravity information. The deepest basement in the study area occurs in the northwestern offshore. This depocenter is oriented NW-SE. In the basin, four fault groups occur: 1) NW-SE-striking basement normal faults; 2) strike-slip faults; 3) inverted normal faults, and 4)...
