| 摘 要： | 铜山岭矽卡岩型铜-多金属伴生金银矿床,产于燕山期花岗闪长岩与泥盆系碳酸盐岩的接触带中。金主要呈自然金形式产于黄铜矿和黄铁矿等硫化物中;银主要呈自然银、辉银矿和含硫盐产于方铅矿等硫化物内。金-铜、银-铅密切相关。成矿物质主要不是来自围岩,而是来自深部。成矿与构造-岩浆活动有关。

| Abstract: | The Tongshanling skarn-type copper-polymetallic deposit associatedwith gold and silver is situated in the contact zone between Yenshaniangranodiorite and Devonian carbonatite. Gold occurs mainly as a native goldin sulfides such as chalcopyrite and pyrite and silver as a native silver,argentite and sulfosalt in sulfides such as galena. Gold is closely relatedto copper and silver to lead. Ore-forming substances are dominantly deri-ved not from country rocks, but from great depths. Mineralization isrelated to tectonomagmatic activity. |
