内蒙古东乌珠穆沁旗(简称东乌旗)地处我国北部边疆,过去这一地区地质研究程度较差,少而零星,且不系统。通过一比二十万区域地质调查,对该区进行了全面系统地研究。发现该区泥盆系出露比较齐全,层位连续,含有极其丰富的化石,是我国北方研究泥盆纪地层、古生物的有利地区之一。笔者参加了该区一比二十万区域地质调查工作,亲自参加测制了地层剖面。经分队全体同志共同努力,华北和东北地质研究所有关同志提供了化石鉴定资料,我们对该区泥盆系重新进行了划分,分为三个统(上统、中统和下统),并新建立了六个组。现由老至新
Inner Mongolia East Wujumuqinqi (Dongwuqi) is located in the northern frontier of China. In the past, the degree of geological research in this area was rather poor, sparse and sporadic, and not systematic. Through one to two hundred thousand regional geological survey, conducted a comprehensive and systematic study of the area. It is found that the Devonian outcrop in this area is relatively complete with continuous layers and extremely rich fossils. It is one of the favorable areas for studying Devonian strata and paleontology in northern China. I participated in the region one to two hundred thousand regional geological survey, personally participated in the measurement of stratigraphic profiles. Through the joint efforts of all the comrades in the detachment, the relevant commenters of the North China and Northeast Institute of Geology have provided fossil appraisal data. We have re-divided the Devonian in this area into three systems (E, CE and X) Six new groups have been established. From old to new
