| 摘 要： | 湘中地区几个主要晚古生代向斜内,二叠系茅口组底部的各种镁质粘土岩分布广泛。在湘潭、湘乡一带该层位主要为海泡石粘土岩,而娄底往西到新化一带变为以蒙皂石族为主的粘土岩。它们对研究该区的沉积环境具有指相作用,并具找矿意义。

| Abstract: | Various kinds of magnesium clayrock in the basal part of Permian Maokou Formation occurred exten-sively in several main Late Palaeozoic synclines in Central Hunan This stratigraphic horizon yields main-ly sepiolite clayrock in the area from Xiangtan to Xiangxiang, and changes gradully into smectite-dominated clayrock from Loudi West ward to Xinhua. They are of facies indication for the sedimentary environment study of the area, and also of prospecting significance. |
