摘要

摘要: 形成于西天山晚古生代吐拉苏火山盆地的伊尔曼得金矿、阿希金矿和塔吾尔别克金矿等3种不同类型金矿,其围岩蚀变及微量元素具有不同的特征.伊尔曼得等金矿类型的围岩蚀变为硅化、高岭石化、重晶石化和地开石化,As、Sb、Hg、Cu与Au含量呈正相关关系.塔吾尔别克金矿类型围岩蚀变为硅化、绢云母化、绿泥石化、碳酸盐化.蚀变围岩的As值增高,Au和Ag的含量明显增高.阿希金矿类型围岩蚀变主要有绢云母化、冰长石化、碳酸盐化、硅化、伊利石化,蚀变岩石的Se和As含量与Au、Ag含量基本呈正相关关系.

Abstract: Yiermande gold deposit,Axi gold deposit and Tawuerbieke gold deposit in Western Tianshan area,formed in Late Proterozoic Tulasu volcanic basin,are three distinct types of ore deposits,with different wall rock alteration features.The wall rocks of Yiermande type of gold deposit produce such alterations as silicification,kaolinization,baritization and dickitization.The contents of As,Sb,Hg and Cu have a positive relation to Au.The wall rocks of Tawuerbieke type show silicification,sericitization,chloritization and carbonation.The content of As in wall rocks raise along with that of Au and Ag.The wall rock alterations of Axi type include mainly sericitization,adularization,carbonation,silicification and illitization.The Se and As contents are positively relaed to Au and Ag in the altered rock.
