摘要
本文通过对膝县煤田晚古生代含煤岩系中发现的各类古生物化石的研究,提出了石炭-二叠系及各统的生物划分依据。并在古生物群特征和岩性特征详细研究的基础上,对膝县煤田晚古生代地层作了进一步的厘定。
By studying emphatically on all kinds of the biotic fossils which has been discovered in the coal-bearing series of late palaeozoic era in teng- xian coalfield this paper presents a more reliable basis for the biotic subdi- vision of permo-carboniferous and other formations. On the basis of detai- led study on properties of palaeozoic biotic group and strata we have made a further revisal to the boundaries of late palaeozoic erathem in Tangxian coalfield
