摘要
石门冲岩组仅分布于河南省商城县石门冲地区红山寨—三洞盖一带,岩性组合为白云母石英片岩、碳质绢云母石英片岩夹白云石质大理岩;其该岩组内部断层和石英脉发育,为不同的岩块拼接而成,与周围地质体均呈断层接触,和龟山岩组第一岩性段围成一残破的构造窗。经岩石类型组合对比及构造分析,认为石门冲岩组为龟山岩组第一岩性段的一部分,后经逆冲推覆构造作用移位至现今位置—形成飞来峰。
Shimenchong Formation located only in Shimenchong area covering Hongshanzhai to Sandonggai of Shangeheng Country, Henan Province, and the rocks muscovaite-quartz schist and carbonaceous sericite-quartz schist sandwiched by dolomite marble. The quartz veins and faults widespreadly developed in the Shimenehong Formation, consisting of different rock blocks, and contacting with its surrounding rocks by fault, and forming a dilapidated structural window with the first rock member of Guishan Formation. Through the analysis of rock type comparison and structure, it is considered that the Shimenchong Formation was a part of the first rock member of the Guishan Formation, and moved to present position by thrust and nappe structure functions, forming the klippe.
