摘要
在安居镇、随州市、均川幅一比五万区调成果的基础上 ,通过广泛综合对比分析 ,认为随南地区武当岩群 (原随县群 )实为“大套有序 ,局部无序”之构造 (岩石 )地层单位 ,由下至上可划分为三个岩石组 :一岩石组 (变沉积岩岩组 )、二岩组 (变火山岩岩组 )、三岩组 (变沉积火山岩岩组 ) ,并对建立三岩组正式组级构造 (岩石 )地层单位名称进行了讨论。
According to the 1:50000 geological mapping data of Anjuzhen Sheet,Suizhoushi Sheet and Junchuan Sheet, this paper proposed that Wudang Rock Group (original Suixian Group) can be regarded as a overall ordered but local disordered'tectono(rock)-stratigraphic unit which can be divided into three rock formations from top to bottom as following:First rock formation( metasedimentary rock formation) , Second rock formation(metavolcanic rock formation) and Third rock formation( metasedimental-volcanic rock formation) whose formal names are discussed as well.
