| 中文摘要: |
| 王下牙老金矿为贫硫化物方解石-石英脉型金矿床,矿体严格受断裂裂隙控制。矿石的有用组分单一,有害杂质少,金矿物主要为自然金。主要的金属矿物为毒砂、黄铁矿,同时也是主要的载金矿物;非金属矿物为石英、碳酸盐矿物。矿石多具自形、半自形、他形粒状结构,以脉状、浸染状构造为主。自然金形态为角粒状、长角粒状,赋存状态以粒间金为主,其次为包裹金,裂隙金仅占8.2%,自然金为显微金。矿石类型以含金方解石-石英复合脉为主,其次为含金构造角砾岩型和含金蚀变岩型。 |
| 英文摘要: |
| The Wangxia gold deposit is a medium size calcite-quartz vein type gold deposit with low-sulfide.The ore body is controlled strictly by fracture.The useful composition in the ore is simple,harmful composition is less and the major ore mineral is natural gold.The major metallic minerals and also the major gold carrier minerals are arsenopyrite and pyrite.The nonmetallic minerals are quartz and carbonate mineral.The automorphic,hypidiomorphic and xenomorphic granular textures are the main ore textures and vein and disseminated structures are the main ore structure.The forms of nature gold are breccia and long breccia.Gold occurs mainly as interparticle grain,secondly is inclusion gold particle,and fissure gold takes only about 8.2%.The native gold is in micro-size.The major ore type is gold-bearing calcite-quartz vein,secondly is gold-bearing tectonic breccia,and gold-bearing altered rock. |
