5. Discussion and conclusions
The diverse regolith-covered terrains are widely distributed in arid
desert peneplains, semi-arid grassland and loess plateaus in northern
and northwestern China, forest covered land in the extreme northeast
part of China, alluvial plains in eastern China and laterite in southern
China. These diverse regolith-covered terrains are unexplored or
under-explored, and are the current geochemical challenges for Chinese
mineral exploration.
