| 中文摘要: |
| 湖南的共生与伴生金约占全省金储量的60%以上.共生金主要赋存于元古界浅变质岩系的韧性剪切构造带,与含矿层和变质作用有关,具层控特征;伴生金则分布广泛,主要与浅成或超浅成岩浆热液活动有关,伴生于各种金属硫化物矿床中,多数形成于燕山期的早、中成矿作用期. |
| 英文摘要: |
| By-product gold accounts for 60% of the total production of gold in Hunan province occurring in W-sb-deposits, Sb-deposit, Sb-As-deposits, As-deposits and Hg-As-deposits and so on as native gold and sub-microscopic gold. It can be divided into two types. The first is distributed in the associated ore deposits, located in the low-grade metamorphic rock series on the either side of Anhua-Xupu-Hongjian fracture and closely related to ductile shear zones. The second is widely distributed in polymetal deposits related to shallow-acidic-magmatic rocks. For the first it can usally constitues gold deposits delinated in the associated ore dpeossits but the second can not. |
