陕西省镇安县青山铁金矿床地质特征研究

Study on geological characteristics of qingshan iron gold deposit in zhenan county, shaanxi province

青山金矿床位于旬阳一镇安盆地,盆地受山阳大断裂的影响,背斜、向斜褶皱的翼部均遭受不同程度的破坏,形成一些层间滑动断层。金矿即产在镇板断裂北侧的背斜翼部和核部层间断层中。矿区出露石炭系、泥盆系地层,断裂、褶皱构造较发育。矿体呈较规则的陡倾斜脉状产出。矿石金属矿物以褐铁矿、自然金为主,次为黄铁矿;脉石矿物主要为石英,方解石。

The Qingshan gold deposit is located in the basin of Xunyang, and the basin is affected by the great fault of the Shanyang. The corners of the anticline and the oblique folds are damaged to varying degrees, forming some interlayer sliding faults. The gold mine is produced in the anticline of the anticline and the nucleus layer of the north side of the fault. The Carboniferous, Devonian strata, faults and fold structures are more developed in the mining area, and the magmatic rocks are mainly composed of shallow intrusive rocks - quartz diorite. Ore body was more regular steep slant pulse output, ore mineral minerals to limonite, siderite, natural gold, times for the pyrite, hematite; gangue minerals are mainly quartz, calcite.
