| 摘 要： | 寺合金矿床位于秦岭褶皱系礼县-柞水华力西褶皱带和南秦岭印支褶皱带的结合部位,受与夏河-临潭-岷县-宕昌-西和-凤县深大断裂斜交的断裂带、印支-燕山期花岗闪长岩体的共同控制.矿床赋存于泥盆系变质砂岩、千枚岩中.矿体呈板状、似板状.矿石为多金属石英脉型,以原生矿为主,近地表为氧化矿石.金属矿物主要为黄铁矿、毒砂、方铅矿、闪锌矿、黄铜矿、褐铁矿.今后应注意在有利的地层(岩性)、有利的构造和岩体周边找金,利用地化剖面在深部找金.

| Abstract: | Shihe Au deposit is situated at the joint of Variscan Lixian-Zhashui fold belt and Indosinian south Qinling fold belt of Qinling fold system. It is controlled by both of Indosinian-Yanshanian granodiorite intrussive and the fractural zones that crosscut the big and deep-seated Xiahe-Lintan-Minxian-Dangchang-Xihe-Fengxian fault and hosted by Devonian metasandstorne, phyllite. Ore bodies are tabular or tabularoid. Ore is dominated by quartz vein type and primary ore. Oxidized ore occurs at near surface. Pyrite, arsenopyrite, galena, phalerite, chalcopyrite, limonite are the main metal minerals. Further exploration should be directed to the favourable layers (lithologies), structural positions and surroundings of intrussives. Geochemical profile can be used to search for ore bodies at depth. |
