摘要
研究新疆210金矿床中黄铁矿产状、形态特征及不同粒级黄铁矿的化学特征和晶胞参数等。结果表明,210金矿床为蚀变破碎带型金矿床,矿石中黄铁矿含量、粒径与金含量密切相关,含量高、粒径小的黄铁矿可作为强矿化标志。通常含金黄铁矿与无金黄铁矿相比颜色加深,晶胞参数轴长加长,亦可作为金矿化找矿标志及贫金、富金的评价准则。矿床具沉积矿床及热液矿床成因特点,初步认为矿床成因属"双源成因",其黄铁矿形成于中深成环境。
In this paper the authors studied minutely the occurrences,shapes,compositions and their typomorphic ratios（Fe/（S ＋ As）,Co/Ni,S/Se）of the pyrites in 210 gold deposit,analyzed the pyrite typomorphic coefficient characteristics,summed up the pyrite genesis and prospecting typomorphic characteristics.210 gold deposit is altered rock gold deposit.Both the content of the pyrite and particle size are closely related to the gold content of the ore.High levels and small particle size could be a strong symbol of pyrite mineralization.Usually containing pyrite and pyrite- free compared to the deepen the color,the long axis of the cell parameters lengthened,it could serve as a gold mine of signs and poor gold prospecting,gold-rich evaluation criteria.The compositions and typomorphic ratios（Fe/（S＋As）,Co/Ni,S/Se）of the pyrites suggest that genesis are both sedimentary and hydrothermal.It is initially considered to be ＂double-genesis＂ type,and this deposit formed in an environment of deep depth.
