摘    要:浅成低温热液金矿床分为冰长石-绢云母型和明矾石-高岭石型两类,主要分布于环太平洋地区、地中海-喜马拉雅带和蒙古-鄂霍次克带,形成了许多超大型和大型金矿床.矿床主要形成于大陆边缘和岛弧环境,与陆相火山岩和火山机构有密切的关系,已发现矿床的形成时间以中、新生代为主.矿化发生于火山作用后,火山体系脆性断裂带和深部侵入体的发育使地下水循环,具有大量成矿流体及成矿物质来源是形成浅成低温热液金矿床的重要条件.

关 键 词:浅成低温热液金矿床  地质特征  成矿模式

Abstract:Adular is commonly distributed in Guliku gold(silver) deposit and can be divided into two kinds according to its occurrence One is that adular and quartz occur in vein like orebody of main mineralizing stage and altered wallrock closed to orebody with subveined or band disseminated shape,the other is that adular occurs in altered andsite and dacite with disseminated or disseminated network shape This adular is the products of altered feldspar minerals in early stage of mineralization Adular is rhombus,transparent biaxial crystal and negative character It is consisted of SiO 2(66 05%),Al 2O 3(17 53%),K 2O(16 04%) and Na 2O(0 25%) by microprobe analysis The discovery of adular has important significance in ore prospecting and metallogenic studying
Keywords:Guliku gold (silver) deposit  adular  geological significance  Daxinganling
