Summary:In order to study the ore-bearing properties of strata and rock masses in Dorniang area, the characteristic parameters, distribution and evolution of elements in each geological unit were analyzed based on 1∶50 000 stream sediment survey.In the study area, Au, As and Sb were strongly differentiated(C_v >1.5),Hg showed differentiation, Bi showed relatively uniform distribution, and other elements showed uniform distribution.In second and third members of Gande formation, Qingshuihe formation and granodiorite, the elements were mostly distributed in low background and poor.The first member of Qingshuihe formation was characterized by strong enrichment of As, Sb, Au and Bi; The enrichment sequence from high to low was Au(2.39)→As(2.31)→Sb(2.15)→Bi(1.24);As(4.01)and Au(2.00)were strongly differentiated.As and Sb in monzonitic granite porphyry were strongly enriched and differentiated, Bi and Au were enriched and distributed, showing characteristics of differentiation, having the potential to search for structural
