Geological & Industrial Significance
Qarhan Salt Lake (蒙古语: "Salt World") formed over 300 million years from evaporated ancient oceans, now holding:
- 600+ billion tons of salts (500B tons NaCl, 5.4B tons KCl).
- Global rankings: World's 2nd largest salt lake (after Utah's Great Salt Lake) and China's largest potassium/magnesium reserve.
- Industrial hub: Produces 80% of China's potassium fertilizer via automated plants like Qinghai Potash Factory.

- A 32km natural salt-crust highway (15-18m thick) floating on brine, supporting trains and trucks.
- Salt Flower Wonderland
- Halite crystals form "coral reefs" and "jade pagodas" due to varying mineral concentrations.
- Emerald Brine Pools
- High lithium content tints waters apple-green (best viewed June-Oct).
