| 摘 要： | 云南新平县鱼塘铜矿位于元谋-大红山铜成矿带南部,矿体呈似层状、透镜状产于古元古界大红山群肥味河组(Pt1 f)和曼岗河组(Pt1m)地层中,地层控矿明显。矿石以隐晶质结构、浸染状构造为主,矿床成因与“大红山铜矿”相似,属于海相火山沉积-变质铜矿床。

| Abstract: | Yutang Cu deposit in Xinping,Yunnan is in the S part of Yuanmou-Dahongshan Cu metallogenesis zone.The orebody is stratoid,lenticular in Paleo-Proterozoic Dahoangshan Group Feiweihe Formation(Pt1f)and Manganghe Formation(Pt1m),ore control of strata clear.The ore is mainly cryptocrystalline,disseminated.The deposit genesis is similar to that of“Dahoangshan Cu depost”,belonging to marine volcanic sedimentation-metamorphic Cu deposit. |
