摘要：

洞庭盆地是湖南省最大的中、新生代陆相红色盆地,面积约15000平方公里,白垩-第三系极为发育。 本文对洞庭盆地近十年石油普查所获白垩纪轮藻化石资料进行总结。化石产地包括洞庭盆地内部的桃源、常德、汉寿、澧县、沅江、安乡、湘阴、汨罗、益阳以及相邻的石门、慈利等地区。

Abstract:

The Cretaceous Charophyte fossils in Dongting basin,Hunan province,can be divided into 4 fossil assemblages from bottom to top.The 1st assemblage (Flabellochara hebeiensis-Aclistochara caii assemblage) is distributed in the Qijiahe Formation,corresponding to Upper Barremian.The 2nd assemblage (Euaclistochara mundula-Mesochara symmetrica assemblage) occurs in the Sanyangang Formation,corresponding to Aptian-Albian.The 3rd assemblage (Porochara gongangzhaiensis-Charites guanpingensis assemblage) is distributed in the Fenshuiao Formation,corresponding to TuronianCampanian.The 4th assemblage (Euaclistochara dongtingensis-Maedlerisphaera minuscula assemblage)occurs in the Yanmatou Formation,corresponding to Mastrichtian.
