Agricultural soils south-west of the Jinding mine
Lanping County, north-western Yunnan, China
Soils
- Type
- Soil
The Jinding deposit, mined on a large scale since the 1980s, mostly by open pit, with a zinc smelter and slag heaps; dust from mining and processing contaminates soils over about 5 km. Transect from 100 to 5000 m; additional sources (tailings dam, underground mines), hence an irregular decrease with distance. Indicative coordinates.
