Title: Characteristics of the copper deposit in Ganluo,Sichuan,China
Abstract: This paper studies the metallogenic features and the mineralization enrichment regularity of copper-silver sulphide diposit.The deposit occurs in the limestone of Maokou Formation and the vicinity of structural fracture belt where the limestone is in contact with basalt in Middle Permian in Ganluo of Sichuan,China.The authors provide a new approach for prospecting in this paper.Through the field geological investigation and mineragraphy characteristics analysis,they discover that the mineral components of the Xinshan copper deposit include chalcopyrite,tetrahedrite,arsenfahlerz,bornite,azurite,associated sphalerite,and galena.The mass fraction of Cu is 1%~10%,Pb+Zn 2%~3%,and Ag 100×10-6~200×10-6.This ore-bearing stratum has been existed before the basalt eruption,with variety of useful minerals components and obvious structural ore-control characteristics.This has obviously nothing to do with volcanic mechanism.In summary,the authors preliminary believe that the deposit genesis is the filling of copper and polymetallic ore magma.This new copper deposit type has a high grade,is large scale,and accompanies rich beneficial elements.It has a great prospecting potential.
