| 中文摘要: |
| 江西马塘地区的花岗岩质硅化破碎带中发育孔雀石化黄铜矿化蚀变石英闪长玢岩、黄铜黄铁矿化次生石英岩,构造带两侧见有多处脉状花岗岩、花岗斑岩出露.推测铜矿化与深部的隐伏斑岩体关系密切;地表显示为花岗岩质硅化破碎带中的裂隙充填型细脉浸染状矿化,深部可能赋存有斑岩型工业铜矿体.本区是寻找隐伏斑岩型铜矿床的有利地区. |
| 英文摘要: |
| The silicified cataclastic zone in granite in Matang area,Jiangxi province is developed with malachitization and chalcopyritization,quartz dioritic porphyrite and pyrite-chalcopyrite-mineralized quartzite.On either side of the cataclastic zone are exposed many dyke-like granite and granitic porphyry.At surface,fissure-filling veinlet-dissemination mineralization is observed in the silicified cataclastic zone.The mineralization is inferred to be closely related to porphyry body at depth where industrial porphyry copper ore body may occur.Matang area is the target for prospecting blind porphyry copper ore deposits. |
