| 中文摘要: |
| 小柳沟铜钨矿床产于朱龙关裂谷带中,矿化主要产于长城系朱龙关群基性火山岩及碳酸盐岩中,层控及岩控特征明显。加里东晚期,由于隐伏花岗岩的侵入,在矿区形成"D"字型穹窿及其断裂构造,含矿热液沿环状、放射状断裂上侵,在围岩中以充填、交代和叠加改造的形式成矿,主要铜钨矿体共4条,呈层状、似层状产出,矿床成因类型为火山沉积 热液叠加改造型。 |
| 英文摘要: |
| Xiaoliugou Cu, W deposit is located in Zhulongguan rifting zone with mineralization occurring in basic volcanics and carbonate rocks of Zhulongguan Group of Changcheng series. It is characterized by stratobound control of ore. During Late Hercynian period the deep intrusion of granitic body caused a "D" form of dome and fracture. Ore fluid flowed up along ring fractures and radiate fractures and to fill fractures or replace wallorcks or rework and superimpose them as ore. There are four stratobound or layered Cu, W ore bodies. This is a volcanic sedimentary-hydrothermal superimposed ore deposit. |
