| 摘 要： | 安徽省绩溪县榧树坑金矿床处于华南板块北东缘的皖浙坳褶带，白际岭-天目山断裂与绩溪-宁国断裂之间。矿区矿体主要赋存于南沱组（Nh2n）地层中，构遣应力下的层间滑动及脆性变形机制下形成一系列张裂隙为成矿提供了运移通道，岩浆的侵入为成矿提供了成矿热液。另外，淋滤作用对本矿床的金的进一步富集也起到了重要的作用。根据地质特征分析，认为榧树坑金矿是火山沉积及后期热液叠加改造金矿床。

| Abstract: | The Feishu Keng gold deposit,Jixi,Anhui lies in the Wan-Zhe depression-folding zone at the northeast fringe of South China Plate,between the Baljiling-Tianmushan fault and Ningguo fault.The orebody occurs substantially in the Nantuo Formation(Nh2n).Interlayer slipping and fragile deformation mechanism under structural stress lead to a series of expansive fissures,which serve as a transmission channel for ore formation.Magmatic intrusion provides metallogenic hydrotherm.Additionally,leaching plays an importa... |
