摘要
本文将广西大容山—十万大山花岗岩岩基划分为4个超单元和22个单元,并根据各单元间接触关系和40个同位素年龄数据,建立了本区花岗岩的地质年代表,即分别形成于早二叠世、晚二叠世、早三叠世和中三叠世等4个地质时代。
In this paper,Darongshan - Shiwandashan granite batholiths in Guangxi are divided into four super -units and twenty-two units. The geological time scale of granites in this area is built on the basis of contact relation between units and fourty isotopic age data. The granites were formed respectively in Early Permian period, Late Permian period, Early Triassic period,Middle Triassic period and so on.
