关于我国西南部相当于纳缪尔期的沉积是否发育?它在石炭纪地层中的位置以及生物群的面貌等问题,长期以来没有得到完满的解决。本文以研究贵州西部下中石炭统菊石类为重点,考虑到共生的其他门类化石及岩性,侧重讨论了黔西早石炭世晚期至中石炭世早期(相当于西欧纳缪尔期)地层的界线、层位及与国外相应地层的对比。
Whether the deposits in the southwestern part of China equivalent to the Mueller period have developed or not? The problems of its location in the Carboniferous strata and the appearance of the biota have not been satisfactorily solved for a long time. This paper focuses on the study of the Lower Carboniferous ammonites in the west of Guizhou. Considering the symbiosis of other types of fossils and lithology, the authors focus on the strata of the early Middle Carboniferous from the Western Qianshi to the Early Middle Carboniferous (equivalent to the Western Eurasian Mule) The boundaries, strata and the corresponding strata and foreign comparison.
