Why is Qinghai a major producer of lithium?

Qinghai is a major producer of lithium primarily due to the vast mineral resources located in the Qaidam Basin, which contains the majority of the province's mineral reserves.1

The basin is characterized by an interior drainage system where rivers discharge into numerous salt lakes and saline swamps. These geological conditions have resulted in the accumulation of rich mineral deposits, including lithium, as well as potassium, magnesium, and other salts. The exploitation of these mineral resources has become a central component of the province's economy, establishing Qinghai as China's largest producer of lithium.21
