山东淄博地区晚古生代植物群组合特征及有关地层划分问题探讨

FEATURES OF THE LATE PALAEOZOIC FLORA ASSEMBLAGES IN ZIBO, SHANDONG, AND DISCUSSION ON THE DIVISION OF THE STRATA CONCERNED

摘要:

山东淄博晚古生代地层出露较好,发育较全,植物化石较为丰富,是研究华北晚古生代含煤地层最好的地区之一。本文对该区晚古生代植物群做了初步研究。根据植物的演替和组合特征,共建立七个化石组合带,用以解决本地区石炭二叠纪地层划分、对比与时代问题。同时,从植物群角度,着重对当前分歧较大的华北石炭、二叠系分界和二叠系上、下统分界的确定以及界线划分原则,提出了自己的见解。

Abstract:

Zibo in Shandong, with the Late Palaeozoic strata well exposed and preserved, and being rich in plant fossils, is one of the idealest region for studying the coal-bearing strata of the Late Palaeozoic era in North China. This thesis is contributed to the preliminey study of the Late Palaeozoic flora in the area. Seven fossil assemblage zones inal have been set up based on the characteristics of the plant assemblages and the plants evolution, which could be used to solve the problems in the division,correla...
