内蒙古吉峰林场东区铅锌多金属矿地质特征及矿床成因

吉峰林场东区铅锌多金属矿区位于大兴安岭主脊铜铅锌银多金属成矿带中北段,塔河—吉峰深断裂带西侧。该矿已圈定铅锌多金属、金多金属两大矿化带,6条铅锌矿体、3条锌矿体、7条金矿体;矿化类型为铅锌多金属、金银多金属组合矿化;矿床成因类型初步认为属浅成低温热液、火山—次火山岩浆热液型矿床。铅锌银多金属成矿作用及金银成矿作用均属燕山晚期。矿区内岩浆、构造活动频繁强烈,矿化及蚀变作用强且普遍,成矿条件优越。

Geological characteristics and genetic analysis on lead and zinc polymetallic deposits in the eastern of Jifeng forest field, Inner Mongolia

Jifeng lead-zinc polymetallic deposit is located in the east of Greater Khingan Range north section of the main ridge Cu Pb Zn Ag polymetallic metallogenic belt, Tahe Jifeng deep fracture zone on the West side. The mine has been delineated, lead and zinc polymetallic gold polymetallic mineralization belt in two large, 6 ore bodies, 3 zinc, and 7 gold ore body. mineralization type Pb Zn polymetallic mineralization, gold and silver polymetallic combination; genetic type of deposit is preliminarily considered that belongs to epithermal, volcano - time volcano magmatic hydrothermal type deposit. Pb Zn Ag polymetallic mineralization and gold mineralization are late Yanshan. In the mining area of magmatic, tectonic activity is frequent and intense, mineralization and alteration of strong and pervasive, excellent mineralization conditions.
