摘要
以重力资料为约束,以LCT软件为平台进行联合,最后得出盆地不存在三叠系、斜波组可能是侏罗系地层,坚实了盆地的资源潜力,进一步推测认为:燕山运动末期,盆地内可能存在着由北向南的挤压反转,反转的前锋带为窑街东正断层,反转的根部是青寺堡,皋兰隆起可能逆冲在永登凹陷之上,盆地为多期次改造的断坳叠合型盆地。
Based on the gravity data, joined LCT software as platform, it is finally concluded that Triassic doesnt exist in the basin and oblique - wave group may be Jurassic formations. It consolidates resource potential of the ba- sin. It is further speculated that extrusion - reversion from north to south may exist in the basin at the end of Yans- han movement; front belt of reversion is eastern normal - fault of Yaojie; mot of reversion is Qingsipu ; Gaolan thrust uplift is over Yongdeng depression; and the basin is a fault sag superposition - type basin which is reconstructed for many times.
