| 中文摘要: |
| 本文通过统计秦家沟土壤样品多元素地球化学参数，推测可能的矿源层和富集成矿作用，分析Grd数据对比图，分析各元素高值区的分布特征，根据相关系数（λ）矩阵的因子分析结果，得到了2个元素组合，推测出本区的主成矿元素和伴生元素，根据R型聚类分析谱系图的统计结果，推测出了本区可能存在的中高温元素组合类型和中低温元素组合类型，确定了本区有利的成矿元素组合类型，圈定了组合异常，通过归一化Grd数据图和组合异常对比，验证异常的合理性和有效性。通过施工地表工程，对所圈定的异常进行了查证，取得了良好的找矿效果，揭示了本区所蕴藏的成矿信息，指明了本区今后的找矿方向，为更好地指导本区下一步勘查工作提供了依据。 |

| Through statistics of multiple-element geochemical parameters in soil samples from Qinjiagou, this work attempts to infer the potential ore source beds and enrichment of mineralization in this area. It is also based on comparison of Grd data and distribution features of high values of all elements. According to the correlation coefficient (λ) of the matrix of factor analysis, it obtains combination of 2 elements and speculates the main mineralization and associated elements in this area. From R-type clustering analysis, the element combination types at moderate-high and low-moderate temperatures are estimated, and the type of combination of ore-forming elements is determined. Then combined anomalies in the study area are delineated. Using normalized Grd data graphs and comparison of the combined anomalies, this work verifies the rationality and validity of these anomalies, which are further confirmed by field surveys. The information from these results would shed a light on the direction of ore-searching efforts in this region. |
