广西平南县平村半隐伏花岗岩岩体侵入于寒武系黄洞口组地层,其西南大部分被泥盆系莲花山组地层所覆盖。该半隐伏岩体以隐爆角砾岩小岩株为露头,在寒武系地层中发育密集的花岗斑岩脉。其剥蚀程度浅,成矿条件好,但地质工作程度低。分析认为在其出露范围内新发现的罗平钨矿具有大型、超大型钨矿床规模的找矿潜力。该半隐伏岩体与钨矿成因上的密切关系对大瑶山成矿带今后的找矿工作具有深远的指导意义。
廣西平南縣平村半隱伏花崗巖巖體侵入于寒武繫黃洞口組地層,其西南大部分被泥盆繫蓮花山組地層所覆蓋。該半隱伏巖體以隱爆角礫巖小巖株為露頭,在寒武繫地層中髮育密集的花崗斑巖脈。其剝蝕程度淺,成礦條件好,但地質工作程度低。分析認為在其齣露範圍內新髮現的囉平鎢礦具有大型、超大型鎢礦床規模的找礦潛力。該半隱伏巖體與鎢礦成因上的密切關繫對大瑤山成礦帶今後的找礦工作具有深遠的指導意義。

Pingcun semi-concealed granite rock mass of Pingnan in Guangxi intrudes into the strata of Cambri-an Huangdongkou Formation,and most of its southwestern part is covered by the strata of Devonian Lian-huashan Formation.The semi-concealed rock mass outcrops as small stocks of cryptoexplosion breccia and develops dense granite dikes in Cambrian strata.This area is characterized by superficial denudation,favora-ble metallogenic conditions and lack of completed geological works.Through analysis,the author believes that it is possible to find a large or super-large scale tungsten deposit in the newly discovered Luoping W de-posit which is located inside the range of the outcrops.This semi-concealed rock mass has close genetic rela-tionship with tungsten deposit,and it has significance in guiding future prospecting works in Dayaoshan met-allogenic belt.
