Abstract

This study aimed to extract the lineaments in the crust of the sedimentary basins of Babouri-Figuil and Mayo Oulo-Lere, (Central Africa) from combined terrestrial and EGM2008 model gravity data. For this, data processing and edge detections were completed using filters. The MGTHG (Modified Gudermannian function) filter was applied because of its accuracy in detecting lateral boundaries of the causative structures. This approach has allowed establishing a new structural map of the study area. This map shows several lineaments detected in the region oriented in the WSW-ENE, NE-SW, E-W and NNW-SSE directions. A comparison of this map with those established in previous studies using other filters shows that in addition to the already existing lineaments, new ones have been detected. This proves that the MGTHG filter produces good results in the region. The results of this study provide new insights in the region’s tectonic framework.
