内蒙古二道河银多金属矿床的发现及其意义

DISCOVERY AND SIGNIFICANCE OF THE ERDAOHE SILVER POLYMETAL DEPOSIT IN INNER MONGOLIA

摘要: 利用大比例尺物、化探综合方法开展多金属找矿，在二道河地区首次发现了银多金属矿床.认为中酸性侵入体与凝灰岩地层接触带、北东向断裂构造、蚀变带及元素组合异常是寻找银多金属矿的直接标志，为大兴安岭森林沼泽区多金属找矿提供了实用、有效的找矿综合方法模式.

Abstract: The Erdaohe Ag-polymetal deposit was found by the comprehensive method of large-scale geophysical and geochemical exploration. The direct indicators for prospecting are the contact between acid-intermediate intrusion and tuff, NE-trending fault, alteration belt and assemblage anomalies of elements. This method provides a practical and effective prospecting model for polymetal deposits in the Daxinganling swamp forest areas.
