摘要
南祁连拉脊山北缘逆冲推覆构造带形成于中新世以后,断面形态呈铲形,各个断层向地壳深部都收敛于一个统一的滑脱面.它的发现扩大了民和盆地油气勘探的领域.
Abstract
The overthrust structural zone on the north margin of the Lajishan Mts.,the southern Qilian Mts.,formed after Miocene,and all the faults like listric shape and converged toward a united detachment sole in the deep crust.It is considered that the discovery of such a structure would expand the oil/gas prospective area in the Minhe Basin
