ABSTRACT: A gravity and magnetic study has been carried out along the continental part of the
Cameroon Volcanic Line (CVL), with the aim to explore the possibility of ore’s
presence into the basement of this region. Different processing techniques have
been applied, including the isostatic residual, the analytic signal and the
Euler deconvolution to compute the Bouguer and magnetic anomalies. Following
Euler solutions (result of Euler deconvolution) and the analytic signal
results, four profiles crossing main structures on the isostatic residual have
been used to enhance the structure of intrusions in the studied area. Despite
the lack of constraints in the studied region, the results show that the
basement is intruded by bodies of different density (2.57 g/cm3 to 2.87 g/cm3), different
size and shape, with depths between 1 and 10 kilometers. These bodies have been
interpreted as old rocks then as potential reservoirs of rare ores. In
addition, volcanic rocks modeled have constituted potential reserves of other
ores like graphite, sulfur, copper, iron.
