Huaihe-Xiaolin area is one of the important mineralization zones of North Huaiyang Au-Ag polymetallic metallogenic belt,of which faulted structures are the main control factors of the deposits.Fractures can be subdivided to four groups according to occurrence: the NW,NE trending,(nearly) S-N trending,(nearly) E-W trending.Different trending faults have different formation mechanism,not only can decide the conduction of magma chamber and ore-forming fluid collection area,but also the migration of ore forming fluids and precipitation places.The gold deposits are mainly controlled by NE-trending faults,followed by the NW-trending and S-N trending faults,while the silver deposits are favorable for N-S trending faults,and then E-W and NE trending faults.This study suggests that Yejiaxiaowan gold deposit and its periphery,Chenjiazhai silver deposit and its periphery are most potential area for further prospecting.
