大巩山西堌堆组蚌埠期褶皱可利用含白云质大理岩透镜体的蛇纹岩作为标志层来恢复,推测其为轴面倒向北的紧密同斜褶皱,S0近南北向,枢纽西倾,地层由东向西变新。
大鞏山西堌堆組蚌埠期褶皺可利用含白雲質大理巖透鏡體的蛇紋巖作為標誌層來恢複,推測其為軸麵倒嚮北的緊密同斜褶皺,S0近南北嚮,樞紐西傾,地層由東嚮西變新。

The Bengbu-period fold in Xigudui Formation in the Dagong Mt is recoverable using dolomitic marble lens-bearing serpentinite as marker bed. It was thought to be a tight isoclinal fold with its axial plane dipping north,S0 al-most NS,hinge plunging west and strata becoming younger to west from east.
