摘要:
卧龙泉金矿床共分3个矿段，分别为独甸矿段、太阳沟矿段和王家崴子矿段。每个矿段由多条金矿带或韧性剪切带组成。金矿带赋存于盖县组一岩段云母石英片岩内，由走向大致平行、规模不等的韧性剪切带组成，呈北西向展布，总长度5 000余m，金品位3.56~31.77 g/t。矿石类型主要为含金石英脉型、含金蚀变岩型和含金角砾岩型；矿体围岩主要是盖县组一岩段含十字云母石英片岩夹黑云变粒岩、浅粒岩、绢云石英岩，以及细晶岩、闪长玢岩、煌斑岩等脉岩，发育不同程度的硅化、黄铁矿化、绢英岩化、绢云母化，外围发育早侏罗世岩浆岩。综合分析认为，卧龙泉金矿床为低温岩浆热液型矿床。勘查过程中，在王家崴子矿段Ⅳ矿带南部和北侧，新发现5条矿体，显示了卧龙泉金矿床深部具有巨大的找矿潜力。

Abstract:
Wolongquan Gold Deposit is pided into 3 ore sections:Dudian Ore Section,Taiyanggou Ore Section and Wangjiawaizi Ore Section.Each ore section is composed of multiple gold belts or ductile shear zones.The gold belts occur in the mica quartz schist in First Member of Gaixian Formation.It is composed of shear ductile shear zones with roughly parallel strike and different scale.It is distributed in NW direction,with a total length of more than 5 000 m and a gold grade of 3.56-31.77 g/t.The ore types are mainly gold-bearing quartz vein type,gold-bearing altered rock type and gold-bearing breccia type;the surrounding rock of the ore body is mainly the staurolite mica quartz schist in First Member of Gaixian Formation,intercalated with biotite granulite,shallow granulite and sericite quartzite,as well as vein rocks such as fine crystalline rock,diorite porphyrite and lamprophyre.Different degrees of silicification,pyritization,sericitization and sericitization developed,and early Jurassic magmatic rocks developed in the peripherals.Comprehensive analysis shows that Wolongquan Gold Deposit is a low temperature magmatic hydrothermal deposit.During the exploration,5 ore bodies were newly discovered in the south and north of ore belt IV of Wangjiawaizi Ore Section,indicating that the deep part of Wolongquan Gold Deposit has great prospecting potential.
