Geochemical survey of stream sediment has become one of the indispensable means in 50000 regional geological survey.Based on the 1:50000 regional geological survey in Yanfeng Shangtianba area,Sichuan Province,this paper conducts regional element geochemical data collection,systematically studies the element background distribution,element enrichment characteristics and distribution characteristics in important ore forming beds,and tests and analyzes 19 elements of Ag,As,Au,Ba,Bi,Cd,Co,Cr,Cu,Ge,Hg,Mo,Ni,P,Pb,Sb,Sn,W,Zn in the area Hg is an important ore-forming element in the area,and 65 comprehensive anomalies have been delineated,including 16 Class A anomalies and 22 Class B anomalies.The verification and evaluation of three important anomalies in the area have been carried out,and it is found that the delineated geochemical comprehensive anomalies are in good agreement with the deposits and ore occurrences(mineralization),providing effective supporting information for the regional prospecting prediction and the establishment of geochemical prospecting models.
