| 中文摘要: |
| 蒙古国矿产资源丰富,但地质勘查程度低。为了探查扎马尔地区找矿潜力,在区内开展了1∶25000土壤地球化学测量工作。依据测量结果,从数理统计学的角度,应用因子分析、相关分析和聚类分析的方法,研究工作区元素地球化学特征。结果表明工作区土壤成矿潜力较大的元素组合有2组,即Au-Ag-Hg和As-Sb,这些元素含量高,变异系数大,反映低温热液成矿作用。对土壤分析元素应用异常下限进行异常圈定,共圈出6个综合异常区,其中综合异常区HT2、HT4、HT6分布受构造控制明显,为下一步优选找矿远景区提供了依据。 |
| 英文摘要: |
| Mongolia is rich in mineral resources, but the degree of geological exploration is low. In order to explore the prospecting potential of the Zamar area, a 1∶25000 soil geochemical survey was carried out in the area. According to the soil geochemical surveys in Zaamar, the methods of factor analysis, correlation analysis, and cluster analysis from mathematical statistics were applied to investigate the geochemical characteristics of the elements in the work area. The results show that there are two groups of elements with greater soil mineralization potential in the work area, namely Au-Ag-Hg and As-Sb. These elements have a high content and a large coefficient of variation, reflecting low-temperature hydrothermal mineralization. The anomalies were delineated by applying the lower limit of the anomaly for soil elements analysis, a total of six comprehensive anomalies were delineated. The distribution of comprehensive anomaly area HT2, HT4 and HT6 is obviously controlled by the structure, which is the preferred prospecting area for the next prospecting work. This study provides a basis for the follow-up prospecting work. |
