香格里拉热林铜钼多金属矿含矿岩体及矿化特征

热林复式花岗岩体,总体为从边部到中部由细粒似斑状二长花岗岩、中粒似斑状二长花岗岩和边部补充期花岗斑岩5个侵入体组成的燕山期同源岩浆结构演化系列.属钙碱性系列,弱过铝质的Ⅰ型向S型过渡特征.成矿类型为蚀变花岗岩、石英脉型和角岩型3种,并划分为黄铁矿±黄铜矿—石英脉,黄铁矿—黄铜矿±辉钼矿—石英脉,辉钼矿±黄铜矿—石英脉及黄铜矿—石英—方解石脉4个成矿作用阶段.

ORE-BEARING ROCK BODY AND METALLOGENESIS FEATURE OF RELIN CU-MO MULTIMETALLIC DEPOSIT,XIANGGELILA

Relin composite granite body is composed of Yanshanian cogenetic magmatic evolution series of generally 5 intrusions of fine grained quasi-porphyritic adamellite, medium grained quasi-porphyritic adamellite from margin to centre and marginal compensation period granite porphyry, characterized by the transition from I type to S type of cale-alkali weak peraluminous rock. The metallogenesis can be divided into altered granite, quartz vein and hornfels 3 types, and pyrite ± chalcopyrite-quartz vein, pyrite-chalcopyrite ± molybdenite-quartz vein, molybdenite ± chalcopyrite-quartz vein and chalcopyrite-quartz-calcite vein 4 metallogenetie stages.
