摘要
论述了兴隆矿区外围推覆构造上覆席体、下伏岩系、推覆剪切滑移带变形特征、构造岩特征和推覆构造形成过程。应用Ramsay等人有限应变测量新方法,估算了推覆位移距离。在推覆体下预测出52km^2的隐伏煤系分布区。
Nappe structure is an important and focal point in the field structure geology. The article deals with in detail not only the deformational characteristics of theoverlying thrust sheet, underlying strata and shear slip zone, but also the tectonites of the nappe structure in the adjacent region of Xinglong Mining Area. Applying the new method measuring confined strain, proposed by Ramsay et al., the displacement of the nappe is calculated approximately. On the above basis, a hypothesis is put forward to explain the development of the nappe structure, and an area of 52km^(2) coal-bearing strata underlying the nappe is prognosticated.
