珠斯楞海尔罕山峰,位于内蒙古额济纳旗,巴丹吉林沙漠以北。上泥盆统岩层围绕该峰的北缘分布,呈西北—东南延伸,西起西屏山,东至依克乌苏一带;出露宽仅2公里,长约10公里,范围虽小,但位置重要。以往内蒙古西部和邻近的甘肃北部未发现过海相上泥盆统的沉积。在获得化石前,这套地层曾被误认为二叠系。1977年,宁夏地质局综合研究队与西安地质矿产研究所二室部分同志共同工作后,获得较丰富的珊瑚、腕足类等化石,证实该区确有上泥盆统下部相当弗拉斯期地层的存在,命名为西屏山组,与我国南方佘田桥组可以对比。
Beilsut Herzog peak, located in Ejina Banner, Inner Mongolia, north of Badain Jaran Desert. The Upper Devonian strata are distributed around the north edge of the peak, extending from northwest to southeast. From the west to the west of Pingdingshan and from the east to the area of Ekwusu, the outcrop is only 2 km long and about 10 km long. Although the area is small, important. In the past, no sediments of the Upper Devonian have been found in the western Inner Mongolia and the adjacent northern Gansu. This fossil was mistaken for Permian before it was acquired. In 1977, the comprehensive research team of Ningxia Geological Bureau worked with some comrades in the second room of Xi’an Institute of Geology and Mineral Resources to obtain richer corals, brachiopods and other fossils, confirming that there is indeed a quite Frasidian formation on the lower Devonian Of the existence, named for the West Pingshan group, with the southern Shetian Bridge group can be compared.
