摘　　要：黄铁矿是与金成矿关系最为密切的矿物之一,其作为标型矿物是寻找金矿床的重要标志之一,利用黄铁矿的晶体形态,化学成分标型特征及热电性在评价金矿床的深部远景、矿床成因等方面都具有重要意义。研究指出,利用黄铁矿的晶体形态标型和热电性特征及微量元素的变化特征可以确立金矿体的分带并指导找矿,利用黄铁矿中Au/Ag、Co/Ni及S/Se比值可以初步判断金矿床的成因类型。The pyrite is one of the most closely related to the mineral with respect to gold mineralization. And it as a standard type of minerals is a important symbol of the gold deposit. The pyrite crystal morphology, chemical composition of standard features and pyroelectricity have important implication on evaluation of gold deposits in the deep vision, GENESIS, etc. The study shows that the standard type of crystal form, thermoelectric characteristics and trace elements variation of pyrite can identify the zoning characteristics of gold ore bodies, and provide the guidance information for future prospecting. The value of Au/Ag, Co/Ni and S/Se in pyrite can be used to deter- mine the genetic types of gold deposits.
