摘要
查明金矿床形成的时空分布的不均匀性,对指导金矿床预测有重要意义。笔者在我国胶东、小秦岭等主要金矿带研究的基础上,从三个方面论述了金矿床成矿演化规律:1)金矿床在地质历史上的成矿演化;2)不同地质作用过程中的成矿演化;3)成矿过程中不同矿化阶段的定向演化。这些规律对优选金矿床勘查靶区和矿床(点)评价都有重要指导意义。
Finding out the chronological and spatial inhomogeneity of gold deposits is important for gold deposits prospection. After studying the main gold mineralization zones in China, the auther presents the evolution regularities of gold deposits from three aspects: ore ?forming evolution of gold deposits in geological history, ore-forming evolution in different geological processes and definite diretional evolution of different mineralization stages in ore-forming process. These regularities are important for optimizing and evaluating the target areas of gold deposits.
