马兰薄皮式推覆构造由Ｆ０９、Ｆ０１分别构成顶、底部推覆构造的边界断层及主滑面，其间包容着１４个断片，向下消失于基底滑脱面之上，构成典型的侏罗山式薄皮构造。外来岩体由北西向南东推覆滑动，滑移距离在７ｋｍ以上，地层长度缩短５倍左右，地层厚度增加３倍。推覆构造产生于Ｊ３ｔ之后，Ｋ１ｄ之前，系燕山运动中晚期，向下切割及叠加在早期Ｆ１滑覆构造系统之上。构造发育规律对找煤勘探具有重要的指导意义。
The Malan thin-skinned thrust structure consists of F09 and F01, which respectively constitute the top and bottom thrust structures of the boundary fault and the main slip surface. During the formation, the Malan thin-nappe structure contains 14 segments and disappears downwards on the base slip-off surface to form the typical Jurassic-style Thin skin structure. The alluvial rock pushes and slides from northwest to southeast, the slip distance is more than 7km, the stratum length is shortened by about 5 times and the stratum thickness is increased by 3 times. The nappe structure occurred after J3t and before K1d, late Yanshanian movement, down-cut and superimposed on the early F1 slip-cover system. The law of tectonic development has an important guiding significance for coal prospecting.
