Characteristics of Tectonic Superimposed Halo and Deep Prospecting Predication in Shuiwangzhuang Super-large Gold Deposit in Jiaodong Area
Jiaodong area is the most important gold metallogenic area in China.Shuiwangzhuang gold deposit is the largest deep super-large gold deposit discovered in Zhaoping fault zone in recent years.It is of great significance to use structural superimposed halo method for deep metallogenic predication for the first time.In this paper,through the collection and collation of previous geological data,combining with the field geological survey,the borehole ge-ochemical data test of Shuiwangzhuang gold deposit has been carried out.It is showed that the common element as-semblage in the ore body is Au,As,Sb,Ag,Cu,Pb,Zn,Bi,W,and the characteristic element assemblages are As,Ag and Cu,in which Au is the main ore-forming element and Cu is the main associated element.Taking the 26 exploration line as the main research object,the analysis of structural superimposed halo theory shows that the leading edge halo characteristic indicator elements are As,Sb,Hg;near ore halo characteristic indicator elements are Au,Ag,Cu,Pb,Zn;tail halo characteristic indicator elements are Bi,Mo,W.The ideal model of structural superimposed halo in Shuiwangzhuang gold deposit has been established,and three predication targets of deep ore bodies have been predicated.
