Based On The Evidence Weight Method Of Gold Resources Research And Evaluation In Southeast Of Fuxin

The study area is located in Fumeng county,the southeast of Fuxin,the north east to strip distribution。Tectonic position is located in the northern of embossment of beizhen-platform subside of Liaoxi-platform fold belt of Yanshanian,the north Sino-Korean paraplatform, also located in the north of arc intrusive rock band,in the north east of Xingcheng-Beizhen,The west for chaoyang dome fold break beam of Fuxin basin,to the east of liaohe basin, north for Inner Mongolia axis; The area outdoor layer belongs to north China yanshan division Chaoyang-Fuxin area, formation are mainly distributed in the northwest and southeast;Magmatic activities mainly concentrated in late archean and Mesozoic Jurassic; In the long historical process, The study area experienced strength different multiple tectonic movement, which is the strongest two large tectonic activity period in late archean metamorphic deformation effect and The subduction of the Pacific plate tectonic deformation caused by the strong effect in Indosinian-yanshanian. The long and complicated geological evolution tectonics and magma activities,the area formed the complicated geological phenomenon, has the very rich mineral resource potential, is an important mineral resources in liaoning, in the region is rich in mineral resources.Through the study of the geological background of the area (tectonic position, formation, structure, magmatic activity), and geophysical and geochemical, satellite image and so on, in addition to the area of the typical ore deposit of research and analysis, on the basis of the analysis of the deposit features and ore-forming regularity, establish ore-controlling factors, the establishment of the gold deposit prospecting model.Evidence weight method is a kind of based on data space position of the relationship Geological statistic method, with the aid of GIS platform to realize the effective forecast and mineral resources evaluation. By using the method to predict gold deposits in the southeast of Fuxin, Combined with the gold deposit prospecting model, selecting the best ore-controlling factors on the area for multiple source information metallogenic prediction, according to the prediction results for delineating metallogenic prospective area. For the region’s next round of metallogenic prediction put forward new ideas and prospecting for ore prospect.
