Discussion on the Mineralization Geological Features and Metallogenetic Model of Jiulong Pb-Zn Deposit Belt

The lead-zinc ore belt of Jiulong district is located in the north of polymetallic ore field,with copper mineralization belt in Yinshan and the south of Beishan's lead-zinc ore belt.It's tectonic position lies in the joint of Tailong and the depression of Qiantang's link,the northeastern margin of the Mesozonic volcanic basin and the northwestern of deep fault zone in northeastern of Jiangxi province.Researched on the spot,the metallogenetic construct setting,region metallogenetical characteristics and geological characteristics have been reveal in this paper.the authors regarded that the magmatite invadeing,which caused by early Yanshan Movement,supplied the heat source during the course of metallogenetic in this area,those faults,which developed in the region,offered good structure condition for mineralization,Shuangqiaoshan stratum provide material source in the process of metallization.The metalization mainly took place at Yanshan period.
