Geochemical Characteristics And Metallogenic Prospective Evaluation In Bajiazi And Pingshan Of Heilongjiang Province

According to the collection and collation of the previous research data from Bajiazi to Pingshan area in Heilongjiang Province,it is found that the study degree in this area is relatively low,lacking systematic geochemical maps of 1:50000,geochemical characteristics analysis and metallogenic prospects evaluation of the study area.Stream sediment geochemical Sill-vey of 1:50000 from Bajiazi to Pingshan area was carried out to delineate geochemical anomalies and analyze the geochemical characteristics such as the symbiotic association of elements.There were 195 single element anomalies and 36 composite anomaly.Using the method of scale ranking to make composite anomaly.The top7 anomalies were ?-12Hs-2,?-12Hs-1,?-12Hs-26,?-12Hs-25,?-12Hs-19,?-12Hs-15 and ?-12Hs-16 respectively.Geochemical soil survey of ?-12Hs-26,?-12Hs-25,?-12Hs-19,?-12Hs-15 and ?-12Hs-16 were carried out.Combined with the mineral characteristics and metallogenic regularity of the study area,three metallogenic prospecting areas(There are a Grade I metallogenic prospecting area,a Grade II metallogenic prospecting area,and a Grade III mineralization prospecting area)were delineated.It preliminarily evaluated the mineral resources in the work area and improved the basic geological data of the research area.
