摘要
After years of mining,the reserves of Jiaodong Linglong gold deposit have been consumed enormously.Therefore,the prospecting of reserve resources has become an urgent problem.In this paper,by using the application of rock geochemical method and choosing the typical ore 47 vein as the object of study,the trace elements related with Au had been tested and the correlation between trace elements and Au had been researched.Then,the concentration coefficient and axial zoning had been calculated and the indicative significance of trace elements to deep Au mineralization had been discussed.Finally,looking forward to some reference can be provided for the prospecting of Linglong gold deposit at depth.Some preliminary recognition as followed that the optimal indicator elements in gold ore body is Au,Ag,Bi,As,Cu,Co,Mo and Sb successively;the axial zonality sequence from top to bottom is As,Pb,Ag,Cu,Hg,Sb,Mo,Ni,Th,V,U,Mn,Zn,Bi,Co and Au;the enrichment coefficient of Au,Bi,Ag is big,Cu and Co is medium,Zn is of relative depletion;and the mineralization prospect of No.47 ore body is good in deep.
