摘要
通过对西秦岭区域成矿特点和区域构造演化阶段的讨论,选择区内主要矿床就控矿地质因素、成矿时代、物质来源等特征进行对比,根据矿床成矿模式概括区域成矿模式。提出新元古代、晚古生代、晚中生代是本区大规模成矿期,对甘肃西秦岭地区成矿环境的分析认识进一步深化,对指导区域矿产评价和预测具有指导意义。
The features of deposits forming and regional structural evolution periods are outlined, the main deposits are selected to be compared in ore - control factors, mineralization epoch, material sources, and regional mineralization mode is generalized in terns of deposits forming modes. It is supposed that the large scale mineralization periods are at Late Proterozoic, Early Paleozoic and Late Mesozoic Era.
