【摘要】 古利库金（银） 矿床中冰长石分布普遍． 按其产出状态， 可分两种： 一种为冰长石与石英一起呈似脉状、条带－ 浸染状分布于矿化主期脉状矿体及近矿蚀变围岩中； 另一种为冰长石呈浸染状、浸染－ 网脉状产于蚀变安山岩、英安岩中． 冰长石呈菱形， 无色透明， 二轴晶负光性． 电子探针分析表明冰长石主要由ＳｉＯ２ （６６．０５％ ）、Ａｌ２Ｏ３（１７．５３％ ）、Ｋ２Ｏ （１６．０４％ ） 和Ｎａ２Ｏ （０．２５％ ） 组成． 文章阐明了古利库金（银） 矿床中冰长石的发现， 具有重要的找矿现实意义和研究成矿作用的理论意义．更多还原

【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更多还原
