| 中文摘要: |
| 以北祁连西段吊达坂水系沉积物测量地球化学特征为研究对象，通过元素含量的概率分布、元素富集与分异、单元素异常、元素相关性分析及异常元素组合等特征的研究，在区内共圈定综合地球化学异常18处，划分出3个铜铅锌多金属找矿远景区，发现矿点4处。研究结果显示水系沉积物测量在北祁连西段半干旱高寒山区找矿效果明显。 |
| 英文摘要: |
| This paper deals with the geochemical characteristics of the stream sediment in Diaodaban area of the western section of the northern Qilian mountain region. The probability distribution of the elemental content, the elemental enrichment and differentiation, the single element anomaly, the elemental correlation and the anomalous element combination are analyzed and studied. 18 comprehensive geochemical anomalies and three Cu-Pb-Zn polymetallic prospecting targets were delineated, at the same time four ore occurrences discovered. The stream sediment survey is effecive for ore prospecting in the semi-arid alpine and cold regions, such as the western north Qilian mountain region. |
