摘要
总结国内１０３个、国外３５个含硫盐矿物金矿床的特征，发现蚀变岩型金矿中出现硫盐矿物的概率较大，为０３４，且以Ｃｕ的硫盐矿物为主，其概率为０６３。含硫盐矿物金矿围岩蚀变类型多样，并以硅化、黄铁矿化、绢云母化为主。探讨了Ａｓ，Ｓｂ，Ｂｉ，Ｔｅ等的活动及硫盐矿物的形成与Ａｕ的释放、搬运、沉淀、富集的内在联系，并指出硫盐矿物的找矿预测意义。
The presence probability of sulfosalt mineral in wall rock alteration type gold deposit attains to 0.34, so it wins the first place of all types of gold deposits. The presence probability of copper sulfosalt minerals is 0.63, and it is the greatest of all kinds of sulfosalt minerals. Based on the study of 103 gold deposits with sulfosalt minerals at home and 35 abroad, the main alteration types are silification, pyritization and sericitization. The relations among the activity of As, Sb, Bi and Te etc., the formation of sulfosalt minerals, and the release, transportation, deposition, enrichment of Au are discussed. The prospecting significances are given finally.
