幔枝构造对小秦岭金矿成矿作用的控制

经数十年的强力开发,小秦岭地区中浅部金矿保有资源量处于濒临枯竭的境地,急需补充新的资源储量,同时亟需开展对深部金矿资源勘查。因此对深部成矿规律研究和成矿预测的开展就显得十分迫切。幔枝构造是近二十余年兴起的新的构造理论,近年来,我们在开展小秦岭金矿田成矿规律及深部找矿预测研究项目中尝试运用地幔柱理论对小秦岭金矿的成矿进行解释,以期对小秦岭金矿田的成矿规律、成矿模式、找矿方向提出新的认识,对以后的勘查工作提供一定的帮助。

Discussion on the relationship between mantle branch structure and mineralization of gold deposits in the Xiaoqinling aren

Afterming for several decades,theupper and middle part of gold deposits in the Xiaoqinling area began to run out,for which new deeper exploration and reserves as well as related study become important.Theory of the mantle branch structure has been proposed for more than twenty yeats.In recent years, we tried to use theory of mantle plume to explain metallogenic process in the Xiaoqinling area during related research program,which will benefit for research of metallogenic regularity model prediction in the near future.
