摘 要: | 石井金银矿位于吉林东南部,矿床赋存在侏罗系屯田营组火山岩、火山碎屑岩中,由2条金银矿化带和14条矿(化)体组成,受火山岩和断裂控制明显,矿化富集作用与火山热液活动有关,矿床成因类型为低硫化型浅成低温火山热液型,工业类型为石英脉-破碎蚀变岩型。利用化探和地质相结合的手段进行找矿是该类型矿产勘查行之有效的找矿方法,多重找矿标志建立和筛选是寻找和发现矿床的重要线索。建议加强对8号矿体的进一步勘查工作。

On the Genesis and Prospecting Pattern of Shijing Gold-Sliver Deposit in Jilin Province |
| |
Abstract: | The Shijing gold-silver deposit is located in the southeast of Jilin Province. It is hosted in Jurassic volcanic and pyroclastic rocks, and is composed of 2 gold-silver mineralization belts and 14 mineralization bodies obviously controlled by the volcanic rocks and fault. The mineralization and enrichment is related with volcanic hydrothermal activity. The oregene-sis of the deposit is low-vulcanized hypabyssal low- temperature volcanic hydrothermal type with quartz vein and fractured altered rock. Combination of chemical and geological prospecting is an effective mean of prospecting for this type of depos-its, and establishing and selection of multiple prospecting indicators is an important clue for prospecting deposits. Further prospecting work at the 8# ore body is suggested to be strengthened. |
