禹州华夏植物群与含煤地层研究

摘要

通过对河南禹州华夏植物群与含煤地层的研究可知,河南省禹州市神垕镇与磨街乡之间的大风口一带,石炭二叠纪含煤地层出露总厚度超过950 m,最多含煤层数达89层,华北与华南所有的含煤层位在这里几乎都可以找到天然露头,成为研究我国华北晚古生代聚煤盆地的一根＂铁柱子＂,对对比河南省煤田地质勘查和地层具有重要的标杆作用.所产植物化石已鉴定有112属306种;其中,137个为新种,分属12个植物类别.此外,剖面上还有多层可用于烧制钧瓷的黏土矿层.%According to the study of Cathaysian flora and coal-bearing strata in Yuzhou,in Dafengkou area between Shenhou town and Muojie village,the total Carboniferous-Permian exposed coal bearing strata thickness exceeds 950m,most of the coal seam number up to 89.We can find a natural outcrop of almost all of coal-bearing positions in northern China and Southern China here.The discover of this Cathaysian flora is a'iron pillar'of North China Late Paleozoic coal-forming basin study,and it plays the role of a pacesetter of coalfield geological exploration,stratigraphic correlation of Henan province.Under identification,the plant fossil excavated here contained 112 genera and 306 species,of which 137 species belong to 12 types of plants.In addition,there are clay beddings which used to fire Jun porcelain.
