四川阿西金矿床金矿物特征研究

Abstract

Abstract:

Axi gold deposit is one of the typical gold deposits in western Qinling metallogenic belt.Gold mineralization is closely related to magmatic hydrothermal and wall rock alteration.The mainly useful composition in ore is gold,and paired useful component is silver.The mainly harmful compositions are As,S,organic carbon.Mainly gold carriers are pyrrhotite,arsenical pyrite,stibnite and morass ore,and the minor is quartz.Mineralization has different metallogenic epochs or ore-forming stages including gold-arsenical pyrite-pyrrhotite-quartz stage,gold-stibnite-Calcite stage,hypergenic stage.Gold in ores are mainly particles,grains gold,and in form of inclusions-gold,interparticle-gold,crevice-gold hosts in rocky minerals and metallic minerals.

Key words: Gold minerals, Gold carriers minerals, Axi gold deposit, Sichuan Province
