以往曾经认为诸广山岩体主要形成于加里东期后来根据同位素年龄数据确认主要由燕山期花岗岩组成。近年来,北京铀矿地质研究所戎嘉树等(1977)及中南二三○研究所刘立均等(1980)所做的工作表明,在过去所称的燕山早期花岗岩中有相当一部份应划归印支期,即三叠纪。 In the past, it was thought that the Zhuangshan massif was mainly formed in the Caledonian period and later was mainly composed of Yanshanian granite according to the isotopic age data. In recent years, the work done by Rong Jiashu et al. (1977) at the Beijing Institute of Uranium Geology and Liu Lichun et al. (1980) at the Institute of Central South China Studies 230 shows that a considerable portion of what was previously called Yanshanian early granite should be classified Indosinian, Triassic.
