Analysis of Soil Geochemical Characteristics and Metallogenic Potential in Huolongmengou Area of Heilongjiang

Abstract

Heilongjiang Huolongmengou area is located in the southern section of the DongwuzhuMuqi-Nenjiang polymetallic mineralization belt, and has a good prospect for exploration prospecting. Based on the results of 1∶10000 soil geochemical measurements, this paper uses the methods of element variation coefficient, thick set coefficient and fractal characteristics to count the geochemical characteristics of 10 elements in Heilongjiang Huolongmengou area. Cluster analysis, factor analysis and fractal method were used to analyze the symbiotic association of elements. The results show that Au, Ag, Cu, As and Mo have high prospecting potential in the study area, and Au may be the main ore-forming minerals in the study area. According to the distribution law of elemental abnormal combination and the geological conditions of mineralization, a total of 7 comprehensive anomalies were circled, and compared with the mineralization geological background and geochemical characteristics of the typical Yongxin shallow into low temperature hydrothermal gold deposit and Duobaoshan spot rock Copper-Molybdenum-(Gold) deposit in the region, and the prospect area of Au-Ag mineralization and the Cu-Au mineralization prospect area of Huolongmengou were divided to provide scientific basis for the next step of prospecting and deployment of the research area.
