新疆阿勒泰多拉金矿矿石组份特征及金的赋存状态

A STUDY ON CHARACTERISTICS OF ORE COMPOSITION AND OCCURRENCE OF GOLD OF DUOLA GOLD DEPOSIT IN ALTAY, XINJIANG

对阿勒泰多拉金矿床的矿石类型、构造和结构、矿石成分、主要矿物—自然金的物化特征,赋存状态及含金主要矿物黄铁矿的特征和矿石中的碲化物等进行了较为深入的研究.

The characteristics of the ore composition, and the type, structure, texture and component of the ore are studied comprehensively. And a relatively deep study is made on the physical-chemical characteristics and occurrence of the main mineral-natural gold, on the typomorphic characteristics of main associated minerals-pyri-te and quartz, and on the newly discovered minerals-calaverite, altaite, volynskite. The natural gold in the deposit is considered to occur mainly as micro-gold and submicro-gold, it belongs to the genesis of middle-low temperature hydrothermal-ism, and underwent matamorphism.
