内蒙古鄂旗嘎仙铁锌多金属异常特征及找矿前景探讨

Discussing on Abnormal Characters and Ore-finding Prospect of Ferro-zinc Polymetal in Eqigaxian of Inner Mongolia

嘎仙铁、锌多金属异常具有异常套合好,峰值高,面积大,具浓集中心的特征。异常分布晚元古界偻勒根河群大网子组(Pt3∈1d)变质砂岩、板岩的破碎带中。其岩浆岩为燕山期中酸性侵入岩为主,为成矿元素提供热源,而区内北西向构造破碎带发育,为矿(化)体提供了生成空间。该区据初步地表揭露发现,具备一定规模的铁、锌、银矿化体多条,因此该区具备较好的找矿前景。

Gaxian ferro-zinc polymetal abnormal has good abnormally shrinking. It＇s peak value is high, and large area has the feature of dense to the center. Abnormal distribution late proterozonic Eon. In the stooped Lurgan River Group in net groups crushed zone of metas and stone and slate, magmatic rock is made up of Yan- shanian middle acidic immerge rock, that＇ s the heat sourer for ore-forming element, and in the area northwest structure crushed zone growth supply living space for ore body. In this area according to preliminary earth surface exposure find that it has certain scale ferro, zinc, silver orebody there, Therefore it has better orefinding prospect at this area.
