摘要: 该矿床是华北板块南缘秦岭——“中央造山带”产于沉积岩系中的重要金矿床之一,Au的主成矿期为“沉积变质期”。成矿作用演化自早古生代始至印支—燕山期,伴随板块构造逆冲带的发展,经历了漫长的“沉积(矿源)→变质(矿胚)→岩体热量影响(中温成矿元素叠加)→逆冲推覆、走滑脆—韧性剪节(矿体成型、初步定位)→伸展构造(破坏矿体、最终定位)演化的历程,与脆—韧性剪切带密切相伴”。应属板块构造逆冲带浊积岩-剪切带型层控金矿床,其快速定位预测标志具普遍性指导意义。Abstract: Ma'anqiao gold deposit is one of mast important gold deposits, occurring in sedimentary strata, in the middle-west part of Qinling——"Central Orogen", China and reaches into a large scale in reserves; and its potential of resources adds year after year. The gold deposit has typical significance in the metallogenic mechanism and evolutionary pattern and can be compared with well known gold deposits of the samp type at home and abroad. Major achievements of the study are as follows.
