中国卡林型金矿床金的赋存状态研究

卡林型金矿的载金矿物主要为黄铁矿和粘土矿物，其次是毒砂和石英。金主要以包裹金形式存在，秦岭地区存在有单体金。金主要赋存在含砷的铁硫化物相中。氧化矿石以游离金大量出现为特征。

Gold Occurrence State of Carlin-type Gold Deposits in China

Golden minerals in Carlin-type gold ore are dominated by native gold and argentiferous native gold of Au-Ag series, havehigh fineness,and are mainly enriched insulfide facies. Generally, the gold occurrence is closely related to ore-forming geologicalsetting.In area where there was intensive tectonic activity, gold minerals have complicated shapes, are dominated by microscop-ic solitary gold. Where tectonic activity is weak, gold minerals are round in shape,are dorninated by submicroscopic inclusiongold.
