沘江上游指位于滇西北兰坪县金顶区的沘江源头河段,长余20km,流域面积约500km~2流域内有近年来探明的我国最大的金顶铅锌矿床。通过化探,圈定了土壤和水系沉积物的金属元素高背景异常带,分布在沘江两侧不同高程的斜坡上。金顶铅锌矿床除主金属 Pb、Zn 外,尚含有可综合利用的 Ag、Cd、TI 等金属元素。在土壤、水系沉积物的金属元素高背景异
The upper reaches of the Hanjiang River refer to the source of the Jiujiang River in the Jinding District of Lanping County, northwestern Yunnan Province, with a total length of 20km and the largest Jinding Pb-Zn deposit in China, which has been proven in recent years in a basin area of about 500km ~ 2. By geochemical exploration, delineated the soil and water sediments metal background high background anomalies, distributed in the slopes of different elevation on both sides of the Han River. In addition to the main metals Pb and Zn, the Jinding Pb-Zn ore deposit still contains such metal elements as Ag, Cd and TI that can be comprehensively used. Metallic elements in soils, sediments of sediments vary in high background
