| 摘 要： | The Middle Proterozoic Jiuling Group,one of the most important geologic unit in the Northwest Jiangxi Terrain,is a kind of Au-bearing formation with a Au-Ag-As association,and its geotectonic setting belongs to the ACM area.Granitification can supply Au with favorable complexing agents.Later granitification os of much more significance in mineralization.Regional Aumineralization includes two types;metamorphic hydrothermal solo-Au mineralization in the northern part and magma gydrothermal superimposed polymetallic mineralization with Au,Ag,etc,being dominant in the southern part.Regional exploration should center aroud the Jiujing Group,small granite bodies of later periods and fault structures,while paying attention to the anomalies of trace elements such as Au,Ag,As,Pb,Zn,etc.

| Abstract: | The Middle Proterozoic Jiuling Group, one of the most important geologic unit in the Northwest Jiangxi Terrain, is a kind
of Au-bearing formation with a Au-Ag-As association, and its geotectonic setting belongs to the ACM area. Granitification
can supply Au with favorable complexing agents. Later granitification is of much more significance in mineralization. Regional
Au mineralization includes two types: metamorphic hydrothermal solo-Au mineralization in the northern part and magma hydrothermal
superimposed polymetallic mineralization with Au, Ag, etc. being dominant in the southern part. Regional exploration should
center around the Jiuling Group, small granite bodies of later periods and fault structures, while paying attention to the
anomalies of trace elements such as Au, Ag, As, Pb, Zn, etc.
