| 中文摘要: |
| 东至县余村金矿是石英脉型金矿床。矿体呈脉状赋存于邓家组岩屑石英砂岩、粉砂岩中,空间上受东西向断裂控制。通过研究金矿地质特征、矿石类型及变化规律、成矿地质条件,认为金矿成因类型为热液型,邓家组地层中伴随多热液蚀变的构造蚀变岩带、含多金属矿物的石英脉是主要的找矿标志。 |
| 英文摘要: |
| The Yucun gold deposit,located in Dongzhi of anhui province,is a quartz-vein-type gold deposit. The ore body occurs as veins in debris quartz sandstone and siltstone of Dengjia Formation, and is spatially controlled by east-west faults. By studying the geological characteristics, ore type and variation law, and metallogenic geological conditions of gold deposits, it is considered that the genetic type of gold deposit is hydrothermal type, and the main prospecting indicator is the tectonic altered rock belt with multiple hydrothermal alterations in the Dengjia Formation and the Quartz vein containing polymetallic minerals. and using metallogenic vacancy theory, we indicates that there is a large prospecting space and prospecting potential in the deep and periphery of the mining area. |
