湘西北天门山地区镍钼矿床铂族元素富集特征及成因探讨

DISCUSSION ON THE ENRICHMENT CHARACTERISTICS OF PGE, REE AND THE GENESIS FOR Ni-Mo ORE DEPOSITS IN TIANMENSHAN AREA NORTHWEST HUNAN DROVINCE

本文从含矿岩系、矿体产状、元素组合和地球化学特征，论述大庸天门山地区下寒武统黑色岩系中镍钼矿床的铂族元素和稀土元素的含量和富集特征，并阐明成矿物质具有多来源。矿床成因类型属同生沉积多金属矿床。镍钼矿床是我国铂族元素矿床类型之一，稀土具有综合利用价值。

Ni-Mo ore deposit is one of the PGE deposit with valuable recovery REE in china Based on ore-bearing rock sequency, occurrances of ore bodies, element association and geochemical characteristics of Ni-Mo ore deposits in the black shale,Tianmenshan Area this paper discusses enrichment characters of PGE and REE. It is set forth that such kind of deposit is of syn-sedimentary polymetal ore deposit.
