Using a density of 2.7 g/cm3 for the crust andremoving a second-degree trend surface for modelling, we determined the residual anomalies. Further investigations providedepth of gravity sources, basement structural trend, nature of intrusive bodies and thickness of sediments in the basin. A negativeanomaly of about -18 mGal near Moulvouday suggests a thickness of sediments of 3.1 km extending north east. A 2.5Dmodelling has been carried out along two profiles P1 and P2. The depths estimated from spectral analysis and 2.5D modelling arecoherent. The combination of the spectral analysis and 2.5 D modelling has led to the demarcation of the Yagoua basin. 2006 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56845305 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.45 |
