DISTRIBUTION FEATURES OF ASSOCIATED ELEMENTS FROM MAOLING－ WANGJIAWAIZI GOLD DEPOSITS

The study on distribution of associated elements from Maoling－ Wangjiawaizi gold deposites indicates that As,Cd,B,Bi,Be,Sn,Pb,Sb are obviously enriching in Maoling gold deposite,in which As,Cd,B ,their enrichment coefficients more than 50, are called highly enriching elements, Bi,Sb,Sn,Be,Pb,their enriching coefficients ranging from 5 to 50,are called medium enriching elements;Pb,Cr,Cd,Zn,Be,Sn,Bi,As are obviously enriching in Wangjiawaizi gold deposit, in which Cd,Bi,As,Pb,Sn,their enrichment coefficients more than 50,are called highly enriching elements,Cu,its enrichment coefficient 6.56,is called medium enriching element.Bi,B,As are highly enriching in ores, which are related to the highly and primitively enriching of these elements in bearing gold country rocks. Correlation analysis,cluster analysis, variation coefficients study and microcopic examination show that Cu,Pb,Zn occur respectivly in chalcopyrite and/or tetrahedrite,galena, sphalerite,partly occur in sulfide such as pyrite,arsenopyrite and so on in the form of isomorphous admixture.Element As occurs in arsenopyrite,partly in pyrite,pyrrhotite,marcasite and tetrahedrite in the form of isomorphous admixture;Sb,Bi occur in tetrahedrite,pyrite,arsenopyrite and marcasite in the form of solid solution mixture;Sn and B occur in pyrite,galena and tetrahedrite in the form of independent minerals; Cd occurs in galena,sphalerite,tetrahedrite in the form of isomorphous admixture;partly Cr,Be and B are related with clay minerals and mica.
