黑龙江霍龙门沟地区土壤地球化学特征及找矿潜力分析

黑龙江霍龙门沟地区位于东乌珠穆沁旗-嫩江多金属成矿带的南段，具有较好的找矿前景。本文以1∶10000土壤地球化学测量成果为依据，利用元素变异系数、浓集系数及分形特征等方法对黑龙江霍龙门沟地10种元素地球化学特征进行了统计，运用聚类分析、因子分析法及分形方法对元素的共生组合关系进行了分析，结果表明：区内Au、Ag、Cu、As、Mo等元素具有较高的找矿潜力，Au元素可能是研究区主要的成矿矿种。根据元素异常组合分布规律及成矿地质条件，共圈定综合异常7处，并与区域典型的永新浅成低温热液型金矿床和多宝山斑岩型铜-钼-（金）矿床的成矿地质背景及地球化学特征进行对比研究，划分出大狼沟AuAg成矿远景区和霍龙门沟Cu-Au成矿远景区，为研究区下一步找矿勘查部署提供科学依据。

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

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.
