Geochemical Anomalies And Prospecting Potential Analysis,Breeding Station Area Inner Mongolia

The research area is located in the northeast of the Inner Mongolia Autonomous Region, which belongs to the middle of Greater Khingan Range, and the geological and mineral exploration degree is relatively low. basisThe Inner Mongolia Autonomous Region district is not a few million on 1:20 coverage area, geochemical data scarcity. The 1:5million soil geochemical survey can not only be intended to fill the area of the lack of information, but also can provide the basis for the area to find a job.Based on the variation characteristics of soil elements abundance characteristics and soil elements in the systematic analysis of the soil element concentration coefficient greater than 1 elements of Bi, W, Pb, Sn, the distribution of elements in soil aggregation,coefficient of variation in soil more than 1 elements of Bi, W, Ag, Mo, Pb, Zn, indicating that these elements are not uniformly distributed in the soil, there is a trend of enrichment.In order to make a more effective and weak anomaly, the background value and the minimum threshold value are obtained, the background value and the threshold value are obtained by the iteration method. The feasibility of this method is verified by Q-Q probability. Finally, combined with the actual geological conditions, the background value and the abnormal lower limit value of the study area are determined. Surfer software was used to draw 10 kinds of geochemical anomaly map. The study found that most of the elements with multiple anomalies including W, Pb anomaly largest, strongest, most has the concentration center. Most of the early Cretaceous element anomaly is mainly distributed in the north east of the study area and intrusive rocks of Lower Jurassic red formation near the contact zone, the formation of multi element concentration center.The characteristics of the soil chemical elements in soil were analyzed. The correlation coefficient of Ag with Bi, Sn, W, Cd was: 0.747, 0.620, 0.746, 0.717, and the correlation between Ag and Bi was the best. By means of R cluster analysis and principal component analysis, 10 kinds of elements are classified into 2 types, F1 is W-Sn-Bi-Ag and F2 is Zn-Pb-Cd group. The combination of W-Sn-Bi-Ag is the main ore forming elements in thestudy area. The combination of Zn-Pb-Cd is a combination of elements with the mineralization.Through the analysis of the regional metallogenic geological conditions and the characteristics of the combination of elements, the final recommendations of the 2 place with a large prospecting potential areas.
