摘要
依据地洼成矿理论对河南省金矿的成矿特点及分布规律进行探讨，认为省内金矿床多属岩浆热液再造富集型多因复成矿床。燕山期重熔型花岗岩浆活动和不同型式、不同规模、不同期次的构造活动控制了金矿成矿的时空分布。分析了金矿床的形成机制，指出了找金的有利地区。
Gold metallogeny and the distribution of gold depoeits in Hena province are studied. Based on the Diwa theory, the gold de-posits are polgenetic compound deposits related to reconstruction- enrichment by magmatic hydrothermal fluid.The distribution of ore de-peits in time and space are controlled by Yanshanian remelting - type granite and structures of differed mode and scale. According to theabove - mentioned studies, the metallogenic mechanism of gold deposits are detailed and the favourable regions for gold prospecting are pointedout.
