Geochemical Exploration Model Of Gold Deposits In Eastern Yangzi Metallogenetic Province

The Eastern Yangzi metallogenetic Province is an important metal producing area.There are many large deposits in the region.The article selected three typical gold deposits,including Jinshan gold deposit,Jilongshan gold-silver deposit and Wangu gold deposit.This paper research from deposit geology,regional geochemistry and rock geochemistry,etc,and than establish the geochemical prospecting model of the three gold deposits respectively.By using the technical method of establishing the typical ore depositgeochemical prospecting model,which is adopted by the national mineral resources potential evaluation project Comprehensive analysed their similarities and differences,and established the geochemical prospecting model of the Eastern Yangzi metallogenetic Province.The auriferous strata of Jinshan gold deposit is ultramylonite in the second lithology section of shuangqiaoshan group of Mesoproterozoic Erathem.Some of the ore body is visible on the surface and mainly controlled by fault.Mineralization is associated with granitioid,The indicator elements for prospecting in regional geochemical exploration are Au,Ag,W.The indicator elements for prospecting in rock geochemical exploration are Au,Co,Mo,W,Ag,As Bi,Ni,Cd,Cu,Pb,Hg,Sb,Zn.In the Jinshan gold deposit,the universal indicator elements for prospecting including Au,Ag,W.The auriferous strata of Jilongshan gold deposit is carbonate rock in the Lower Triassic.The ore body is visible on the surface and mainly controlled by fault Structuresand drapes.Mineralization is associated with Jilongshan pluton The indicator elements for prospecting in regional geochemical exploration are Cu,Mo,Ag,Bi,Pb,Zn,B,As,Cd,Sb,W,Au,W,Au,Hg,Li,Th,U,Ni,Y.The indicator element for prospecting in rock geochemical exploration are Cu,Ag,Bi,Mo,Cd,Zn,Au,W,Cr,Pb,Sb,Sr.In the Jilongshan gold deposit,the universal indicator elements for prospecting including Au,W,Mo,Bi,Cu,Pb,Zn,Cd,Ag,Sb,Cr,As,B.The auriferous strata of Wangu gold deposit are silt-slate,metamorphic tuffaceous slate and packsand in the Mesoproterozoic lengjiaxi group.The ore body is visible on the surface and mainly controlled by fault.The indicator elements for prospecting in regional geochemical exploration are Au,As,Sb,Li,V,Co,B.The indicator element for prospecting in rock geochemical exploration are As,Au,Sb,Co,Cu,Ni,Pb,Ag,Bi,Zn,W.In the Wangu gold deposit,the universal indicator elements for prospecting including Au,As,Sb,Co,B,Bi.The universal indicator elements for prospecting gold deposit in Eastern Yangzi metallogenetic province with similar geological background including Au,W,As,Ag,Bi,Sb.
