甘肃金山、马泉金矿床对比研究

金山、马泉矿床定位于礼县—白云—山阳大断裂西段膨大、分支锐角夹持区,通过对矿床区域地质背景、地质特征、成因等要素的对比分析,认为矿床地质特征相似、成因相同或类似。金山、马泉金矿的金源很可能来自中石炭统;硫来自深部,可能由岩浆水提供;成矿热液水由大气降水与岩浆水、变质水混合而成;矿床是在中低温、弱酸性、弱氧化—还原介质、弱矿化度条件下形成的微细浸染型热液金矿床。这2个矿床应为同一个矿床,在以后的地质勘查中应统筹考虑(特别是2个矿床的结合部),扩大现有矿床规模。

A Comparative Study of Gansu Jinshan and Maquan Gold Deposit

Jinshan and Maquan gold deposits are located in Lixian-Baiyun-Shanyang deep fault between swollen west section and branch acute angle clamp area.According to the comparative study of regional geological setting,geological characteristics and metallogenic genesis,we think that it have similar geological characteristics and deposit genesis.Jinshan,Maquan gold resources is likely to come from the Carboniferous;sulfur come from depth,it may be caused by magmatic water;ore-forming hydrothermal water come from mi...
