摘要
湖南省内形成于加里东期的花岗岩为省内花岗岩的重要组成部分,年代学资料显示其形成于加里东晚期。在对近年来省内加里东期花岗岩类的研究进展进行调研与野外资料的基础上,本文总结了省内加里东期花岗岩的特征,列举了一系列与之有成因联系的矿床。省内加里东期花岗岩依据矿物学和岩石学等特征可划分为两个亚类,其中第二类花岗岩越城岭岩体、苗儿山岩体,万洋山岩体和彭公庙岩体具有相似的地球化学特征,且岩体内产出有形成于加里东期的钨(锡)矿床,显示了优越的成钨能力,表明省内加里东期第二类花岗岩岩体的形成与其内部广泛的钨(锡)金属矿床存在直接联系。
Granites formed in Caledonian period are a very important component of granites in Hunan.The geochronological data show that they were formed in the late Caledonian.Based on some newly discovered Caledonian granitic intrusions,and field data accumulated in recent years,the characteristics of Caledonian granites in Hunan are summarized,and a series of genetic related deposits listed.Caledonian granites in Hunan are divided into two subtypes on the basis of its petrological and mineralogical peculiarities.The second subtype,with very similar geological and geochemical characteristics,and good capacity of tungsten mineralization,including Yuechengling,Miaoershan Wanyangshan and Penggongmiao granites,shows superior tungsten mineralization capacity.It indicates that the widespread tungsten(tin)metal deposits related directly with Caledonian granites in Hunan.
