More and more largescale sedimenthosted gold deposits are discovered and explored in PbZn ore field in China to which a extensive attention has bee n paid. (Volcano)Sedimenthosted PbZn deposits can be divided into three ty pes :(1)MVT,(2)VMS,and (3)Sedextype which occur in given tectonic settings,respe ct ively. And gold mineralization is linked to a special thermotectonic event. Th e i ntensive research showes that sedimenthosted gold deposits are only formed in t he region with late extensive thermotectonic event in which the Sedex and VM S type PbZn deposits are occurred ,but MVT does not.So,the region located Sedex  and VMStype deposits are the favourable prospects for gold deposits,and MVTh os ted region is not.
