| 英文摘要 | The development of sedimentary layers in offshore salt-bearing basins in the central segment of west Africa is closely linked to elements such as faults, igneous rocks and crustal thickness. To investigate their spatial relationships, we analyzed gravity and magnetic data in the oceanic areas, and employed edge detection, correlation analysis, and inversion techniques to study the characteristics of these geological elements. Our findings revealed numerous faults and igneous rocks in the crust underlying these non-volcanic continental margins, and these faults and igneous rocks continued to indirectly influence basin sedimentation since the rift period. On the basis of the thickness of the crust and sedimentary layers, we classified the offshore basins into four types of secondary structural units. Combined with the characteristics of faults and igneous rocks, we concluded that the exhumed bulges within the Western Uplift Zone are favorable for oil and gas exploration. |
