摘　　要：近十余年来,现代金矿成矿理论研究取得了长足进展,总结这些进展有助于开阔金矿研究和勘查思路。深入地研究了地球动力学背景对金矿成矿的控制,建立了区域成矿学的基本理论,提出了造山带型金矿的概念。岩浆热液和变质热液成矿理论获得了新的证据,在金矿成矿作用过程中岩浆流体较普遍存在,变质去挥发分作用所产生的大量热液是金矿成矿所需的低盐度流体。全球超大型金矿以中温热液型、浅成火山热液型金矿及砂金矿最为多见。从成矿系列理论发展到成矿系统理论,强调了金与其他矿产资源之间的相互联系,提出了铁氧化物型铜 金矿床和钨 锡成矿省内与侵入体有关的2种新类型金矿床。提出金的宇宙来源及撞击成矿理论。Some great progress on modern metallogenic theory have been made during the last ten years.Summarizing the progress is helpful to extend the thoughts of study and exploration on gold deposits. More research works have been done on how that geodynamic setting controls gold metallogeny. Basic theory of regional metallogeny has been established. Theory of orogenic gold deposit was put up.New evidence for magmatic and metamorphic hydrothermal metallogeny has been found, that is magmatic fluid exists more popularly during gold metallogenic process.Low-salinity fluid produced during metamorphic devolatilization is necessary to form many hydrothermal gold deposits.Most of superlarge gold deposits are mainly mesothermal,placer and epithermal type deposits.Metallogenic systems evolves from metallogenic series and emphasize on the relationship between gold deposits and other mineral resources. Two new types of gold deposits,iron oxide-copper-gold and intrusive-related gold deposits in tungsten and tin province are put forward.Theory that gold originates from the universe and impact metallogenic process has been put forward.
