摘要: 论述了雪峰山西北部喜眉山逆冲—推覆构造的几何学、运动学特征，并用方解石ｅ双晶求得逆冲—推覆构造断层岩形成时的差异应力为１００～１２５ＭＰａ，变形温度为１５０～２００℃，逆冲作用主要发生于燕山运动时期。Abstract: The present paper reviews the geometrical and kinetic characteristics of the Ximeishan thrust nappe structure in the northwest Xuefeng Mountains The differential stress for the formation of faulted rocks in the structure obtained by using the twin striation （e） in calcite is 100～125 MPa;the deformation temperature is 150～200℃ The main epoch of thrusting is Yanshanian
