| 中文摘要: |
| 河北省牛圈银(金)矿床受控于NNE向的牛圈—老虎坝(F1)断裂,隐爆贯入角砾岩是矿床的主要含矿岩石;矿床围岩蚀变发育,主要有钾化、硅化、绢云母-水白云母化、高岭土化、蒙脱石化、绿泥石化和碳酸盐化;围岩蚀变以矿体为中心,可分为4个带(硅化带、绢云母化带、绿泥石-碳酸盐化带和钾化带),构成一个完整的蚀变晕;文章还对蚀变岩中的矿物转化和蚀变岩形成机理进行了探讨。 |
| 英文摘要: |
| Niujuan silver (gold) deposit is controlled by NNE-trending Niujuan-Laohuba fault and hosted by the injected crypto-explosive breccia. The wall rock alteration consists of potassium alteration, silicification, sericitization-hydromica ateration, kaolinitization, smectitization, chloritization and carbonatization and is divided into 4 zones, i.e. silicification, sericitization, chlorite-carbonate and potassium alteration from the center (ore body) towards the outside. |
