| 摘 要： | 金豆子山铅锌矿赋存于华北地台北缘、白云鄂博裂谷带中的中元古界白云鄂博群地层中,属中低温热液矿床,受断裂破碎带控制。该矿床地表已控制的Ⅰ号矿带为矿床的主矿带,Ⅱ、Ⅲ、Ⅳ号矿带为隐伏矿带。矿石储量670多万吨,铅锌金属量约24万吨,平均品位铅1.85%,锌1.65%。围岩蚀变有褐铁矿化、硅化、绢云母化、绿泥石化、含铁锰碳酸盐化等。今后找矿的方向为金豆子山倒转背斜的断裂破碎带内,进一步勘查有望找到成因类似的铅锌矿床。

| Abstract: | The Jindouzishan Pb-Zn deposit is located in the Bayan Obo rift zone on the northern margin of the North China platform and confined to the Middle Proterozoic Bayan Obo Group.The deposit belongs to meso-epithermal one controlled by fault fractured zone.The ore reserve is estimated at 6.7 Mt with average grade of 1.85% Pb and of 1.65% Zn.Wallrock alterations such as limonitization,silicification,sericitization,chloritization and ferromanganese carbonation are well developed.The fault fractured zone in the Jindouzishan reversed anticline is range of reconnaissance in the future. |
