摘要
根据北京周口店太平山区石炭一二叠纪含煤岩系煤层及其围岩的变形、变质特征,讨论了煤层中的顺层韧性剪切带的成因及其物质组成、基本特征、形成条件与地质模式。
According to deformational characteristics,metamorphic traits of the coal layer and their country rock in carboniferous -permian coal -bearing formation at Taiping mountain area of Zhoukoudian in Beijing,This paper discusses the origin ,material composition,basic characteristics,forming-conditions and geological model of the layer-paralled ductile shear belt in coal layer.
