摘要
从区域大地构造演化角度阐述了研究区的金矿成矿大地构造环境，及在不同成矿地质环境中产出的主要金矿床类型，代表性金矿床地质特征。从金成矿的地质背景、构造环境和岩浆活动等方面，结合地质事件和成矿作用的时间演化，总结了金矿成矿地层控矿规律、构造控矿规律、岩浆岩控矿规律和矿床时间分布规律。
This paper deals with the metallogenic tectonic environments of gold deposits in the research district according to its regional tectonic evolution,and principal types of gold deposits occurring in different geological environments,and describes the geological features of typical gold deposits.From the geological backgrounds,structural environment and magmatic activities of gold metallogeneesis,combining with the analysis of geological events and time evolution of metallogenesis,the authors have summarized the orecontroling regularities of strata,structures and magmatic rocks of gold metallogenesis and the time distribution regularity of deposits.
