内蒙古达茂旗巴特敖包一带的志留—泥盆纪地层,分布较集中,出露尚良好。主要为一套正常浅海相碎屑岩夹碳酸盐岩,化石丰富,种类繁多,是研究我国北方志留—泥盆纪地层学的重要地区之一。 1960年,李寿耆、赵泽国等同志在本区发现了这套志留—泥盆纪地层,并在西别河东岸测制剖面、采集化石,又在附近作了路线调查,建立了西别河组,确定其时代为中泥盆世。1965年,内蒙古地质局区测队六分队在本区测制了一些剖面,认为西别河组之上还有一套巨厚的地层,遂又创立了查干合布岩组、哈力齐岩组、艾不盖河岩组、格少可布岩组和 The Zhili-Devonian strata in Badaoobao, Inner Mongolia’s Damaoqi area are more concentrated and are still well exposed. It is mainly composed of a set of normal shallow marine clastic rocks with carbonate fossils, rich in fossils and various in variety. It is one of the most important areas for studying the Silurian-Devonian stratigraphy in northern China. In 1960, Comrades Li Shizi and Zhao Zeguo discovered the Silurian-Devonian strata in this area. They measured the section on the east bank of the Xibei River and collected fossils. In addition, they made route surveys in the vicinity and established the west Do not River Group, to determine the era of the Middle Devonian. In 1965, the Sixth Detachment of Inner Mongolia Geological Bureau measured some sections in this area, and believed that there was a huge set of strata above the Xibiehe Formation. Thus, the Qagan Hebubu Formation and the Haryi Rock Group, Ai not cover the river rock group, grid less Kebu rock group and
