摘要:
本文根据区域地质调查工作,近年来科研成果基础上,对诸广山地区的复式岩体产出地质条件、相互穿插关系、同位素年龄资料等,进行了系统的查证与核实,将该区复式花岗岩体划分为加里东、海西、印支、燕山四期,9个侵入阶段,11个岩浆岩单位。
Abstract:
The Zhuguangshan composite massif is located on the Hunan-Jiangxi-Guangdong border region, covering an area of about 5000 km~2. On the basis of the contact relationships between the massif and the sedimentary（metamorphic） rocks and nearly 100 isotopic age data, 4 periods of intrusive rocks have been distinguished, i.e. the Caledonian, Hercynian, Indosinian and early Yanshanian periods, of which the Caledonian, Hercynian and early Yanshanian periods may be each subdividedinto into the second and third stages and the Indosinian period three stages. The second stage of the early Yanshanian period may be further subdivided into three successive intrusions. There are a total of four periods, nine stages and eleven age units of magmatic rocks.
