摘要
The ore body is controlled by the nearly NS fault silicification fracture zone.Lower Devonian Lianhuashan Formation Upper Member is the ore-bearing wall rock.According to the study of metallogenetic material origin,trace element and metallogenetic condition,we think the Cu multimetallic deposit is caused by many factors.The multiphasic tectonic movement and magmatism are the key factors of supplies of metallogenetic material activization heat source and a part of metallogenetic material.It is a ore deposit of low T hydrothermal sulfide filling-metasomatic type in fracture zone.
