摘要
松潘—摩天岭金成矿带位于川、陕、甘三省交界处,阳山金矿是近年在该成矿带上发现的一超大型岩金矿床。对其地质特征研究表明,除受构造控制外,岩浆岩、地层对矿床也有一定的控制作用,属浅成低温热液蚀变岩型金矿床。下一步找矿主要利用地物化遥等手段进行综合找矿,逐步解剖Ⅰ级—Ⅱ级—Ⅲ级远景区,寻找有望靶区,在找矿思路上要从矿床类型上突破,优选次序是破碎蚀变岩型—微细浸染型—石英脉型,应加强对含矿构造安昌河—观音坝主破碎蚀变带,尤其要加强其南北两侧及深部的研究和勘查。
Songpan - Motianlin mineralizing belt is located in the juncture area of Sichuan, Shaanxi and Gansu provinces. Yangshan gold deposit is a superlargo deposit found in the belt. The deposit is controlled by magmatic rocks and strata besides structures, and belongs to hypabyssal epithermal alteration rock type. Next step ore prospecting in the area will be focused on grade Ⅰ to grade Ⅱ then grade Ⅲ perspective regions to find hopeful targets using synthesis prospecting methods of geophysics, geochemistry and remote sensing. Train of thought for ore prospecting is mainly concentrated on ore type, a priority order is structure - controlled alteration rock, micro - disseminated and quartz vein types. Ore prospecting will be strengthened in the Anchangbe - C, uanyinba main structure alteration belt, particularly in the both sldes and depth of the belt.
