Structural Interpretation of Deep Structures of the Adamawa Plateau (Nord-Cameroon) from Combined Terrestrial Gravity Data and GRACE Model

Bouba Apollinaire, Mono Jean Aime, Oyoa Valentin, Kamguia Joseph

Abstract: In this study, a new structural map of the Adamawa plateau was produced. The multi-scale method of the horizontal gradient has been applied to the combined gravity data of the study area. These data are the combination of terrestrial gravity data and GRACE gravity ones computed from GGM02C model. Upward continuation at different heights was first applied to the dataset and horizontal gradient was later applied at each continuation height to issue a resultant grid which highlighted high gradients that corresponds to the lineaments. Our results confirm the existence of deep structures already recognized or assumed by the classic geological studies and highlights new accidents, an unknown geologically dense unit, never identified by any previous study. The structural map shows that the faults system of the Adamawa plateau is organized in NE-SW and NNE-SSW a direction which is associated to the Cameroon Volcanic Line.
