| 摘 要： | 华北陆台大多数的金矿床均产在绿岩带及与之有成因联系的岩浆岩中。绿岩带金矿可划分为原生金矿床和再生金矿床两类。原生金矿床可细分为层控金矿床和脉状金矿床，再生金矿床主要为与交代重熔岩浆作用有关的热液金矿。地层岩性、构造和岩体是绿岩带金矿的主要控矿因素。绿岩带金矿成矿物质主要来自深部，成矿流体为富含ＣＯ＿２的多成因混合热水溶液。成矿作用常是多期、多阶段。华北陆台绿岩带金矿同世界绿岩带金矿相比，既有相似性，又有独特性。

| Abstract: | Most gold deposits in North china Platform occur in the greenstone belts and magmarocks related to greenstone belts,The gold deposits which occur in the greenstone belts maybe divided into the primary and regenerated gold deposits.The primary gold deposits may bedivided into two stibdivisions-stratabound and gold-bearing lode gold deposits,The regener-ated gold deposits mainly are anatexis magmatic hydrothermal gold deposits related tometasomatic remelting process the stratigraphic rocks structures and rock bodies are prima-ry control factores of gold metallogenesis.The mineragenetic materials were from deepsources mainly.The ore-forming fluids were CO_2-rich mixed hydrothermal solutions of mul-tiple sources.The mineralization often are multi-periods and multi-phases gold deposits ofgreensrone belts in North China Platform are not only similar,but also distinct to that inthe world. |
