| 摘 要： | 新疆北部阿尔泰地区金矿床发育.根据金矿床在成矿作用、主要控矿因素、矿石建造和组构、容矿岩石建造等方面的特征划分为2种金矿类型：造山带型金矿床和浅成低温热液金矿床.2种类型金矿床具有不同的矿化特征，受不同的构造类型控制.浅成低温热液金矿床受火山构造及脆性断裂控制，可进一步划为2种亚类型：高硫型和低硫型.造山带型金矿受韧性剪切带控制，也可划为2种亚类型：一为石英脉型，另一种为蚀变岩（糜棱岩）型.区内金矿床形成于3个时期：高硫型浅成低温热液金矿床形成于石炭纪，造山带型金矿床形成于二叠纪，低硫型浅成低温热液金矿床形成于中生代，并分别对应于海西期碰撞造山阶段、后碰撞造山阶段及中生代稳定陆块发育的地球动力学环境.

| Abstract: | Two types of gold deposits in Altay Mountain, Northern Xinjiang are classified on the basis of metallogenesis, principal ore-controlling factors, mineralogical association, structure and texture of ore and nature of host rock assemblage. The two types involve orogenic belt gold deposit and epithermal gold deposit. The former is controlled by ductile shear zone and subdivided into two subtypes of gold ore (quartz vein type and altered rock type). The latter, controlled by volcanic structure and brittle fault... |
