内蒙古巴丹吉林沙漠北部地处中蒙边境。该区泥盆系发育甚好,沉积物以碎屑岩为主,夹少量碳酸盐岩和火山碎屑岩,含较丰富的底栖生物化石。1960年,宁夏地质局区调队修泽雷等进行1:20万区域地质测量时,于该区首次采得 Disphyllum,Endophyllum Ca- lceola,Atrypa,Tylothyris 等珊瑚、腕足类化石,并将含化石地层置于下中泥盆统。斯后, 宁夏地质局与西安地质矿产研究所于1977—1978年组成地层队对该区泥盆系进行了综合
Badain Jaran Desert in northern Inner Mongolia is located in the border. The Devonian developed very well in this area. The sediments are mainly clastic rocks with a small amount of carbonate rocks and pyroclastic rocks and abundant benthic fossils. In 1960, Ningxia Bureau of Geological Survey Regiment Xiuze Lei 1: 200000 regional geological survey, the first acquisition in the area Disphyllum, Endophyllum Ca-lceola, Atrypa, Tylothyris and other coral, brachiopods fossils, and will contain fossils The formation is placed in the middle Devonian. After that, the formation of strata from 1977 to 1978 in Ningxia Bureau of Geology and Xi’an Institute of Geology and Mineral Resources carried out the synthesis of Devonian in this area
