Geological Characteristics and Exploration Symbols of the Hongliugou Copper Deposits in AltynTagh
摘要
Abstract
Hongliugou copper deposit is located in the northern AltynTagh tectonic belt,and produced in Matekebulake Group of Jixian System.The footwall rocks of ore body are meta-siltstone,meta-ferruginous felsic sandstone layer,which are overlaid by andesite-basalt,with the basic-ultrabasic rock body developed under the foot wall rock.The mineralization has close relationship with andesitic basalts,the ore bodies are controlled by strata,and the mineralizationis unstable,which is occurred as intermittent stratoid and lenticular shapes.Pyrite,pyrrhotite,chalcopyrite,chalcocite and borniteserve as the main ore minerals.Banded,brecciated textures and colloidal structures are often seen in these ore rocks.Comprehensive analysis shows that Hongliugou copper deposit hadformed in the volcano rock during the pre-enriching process and experienced late tectonic and hydrothermal activity,thus this deposit belongs to sedimentarystructural-hydrothermal-reconstrcuction type.After researching as well as contrasting the analyzed results,it is found that some symbols can be utilized as exploration marks,such as zonal intrusive rock symbols,stratum symbols,the characteristics of wall rock alteration and geophysical anomalies.关键词
