分散元素矿床类型、成矿规律及找矿-综合利用方向

TYPES OF DISPERSE ELEMENT DEPOSITS AND THEIR ORE-FORMING REGULARITY AND ORE-SEARCHING AND COMPREHENSIVE UTILIZATION DIRECTION

对我国86个大-中型矿床(铅锌矿床30处、铜矿29处、钼矿14处、金矿6处、铝矿2处、钨矿2处、锡、铁、煤矿各1处)内分散元素地质调查、分散元素查定基础上,着重从成矿地质条件、成矿物质来源、成矿机制、赋存状态划分了伴生分散元素金属矿床的类型和分散元素独立矿床的类型。对各类型矿床内8种分散元素(Cd,Ge,Ga,In,Tl,Se,Te,Fe)的存在形式,进行了单矿物提纯、岩矿鉴定、化学定量分析、X光衍射分析、电子探针分析、形成温度测定。总结了各类型矿床分散元素的成矿规律,指出了找矿-综合利用方向。

Based on the geological survey and data collection of 86 ore deposits, which include 30 Pb-Zn deposits, 29 Cu deposits, 14 Mo deposits, 6 Au deposits, 2 W deposits, 1 Sn deposit, 1 Fe deposit and 1 coal deposit and are accompanied by disperse elements, and their geological and matallogenic condition, ore material sources and the occurrences of the disperse elements are classified into types of the metal deposits with disperse elements as by-product and the independent disperse element deposit. Facing to occurrences of the 8 disperse elements of Cd, Ge, Ga, In, Te, Se, Te, Fe purification of mono-minerals, electronic probe analysis and determination of ore-forming temperature are carried out to sum up concentration regularity of the disperse elements and point out therir comprehensive utilization directions.
