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.
