合肥盆地地质构造复杂,地表沟壑纵横,通过对重力异常目标处理,揭示基底特征及断裂、构造发育情况,认为本区南北分区,"众凹环隆"。该文应用重、磁、电、震等综合物探资料,将本区划分为前陆冲断带、舒城前渊沉降带、六安前隆断褶带和肥北隆后斜坡带4个勘探区带。指出了下步勘探方向和勘探前景。
The geologic structures is very complex and the surface is a crisscross network of gullies in the Hefei Basin. The basement, faults and structural framework of the basin were revealed in accordance with the object-oriented processing of gravity anomaly. The basin can be divided into four different structural belts,i.e., the foreland thrust fold belt, the Shucheng foredeep belt, the Liu'an fore-bulge fault-wrench belt and the Feibei back-bulge slope belt based on integrated gravity,magnetic, electric and seismic data. The prospects for petroleum exploration in the basin were briefly discussed.
