GEOCHEMICAL CHARACTERISTICS AND METALLOGENIC PROSPECTIVE PROGNOSIS OF FUKESHAN REGION IN HEILONGJIANG PROVINCE BASED ON STREAM SEDIMENT SURVEY

The preliminary study of the geochemical features of Fukeshan region was based on the 1∶50 000 stream sediment survey.Through a study of the element distribution features,the authors hold that the area has the potential of finding Au,Pb,Cu and Sb ore deposits and mineralized bodies.The study of the anomalous characteristics combined with the ore-forming geological conditions and existing mine information shows that there exist two main metallogenic types in this area: one is probably gold deposits related to quartz veins in granite,and the other is probably Cu,Pb and Sb polymetallic deposits related to basic-ultrabasic rocks and the metamorphic Xinghuadukou Group.Then the authors divided the study region into Fukeshan,west side of Fukeshan River,and Dalin River gold metallogenic prospective areas as well as Huoluotai River,Huoluotaichiku River,and Huoluotaishan Cu,Pb and Sb metallogenic prospective areas.
