In the map, we can see the map of Hydrogeological map of Inner Mongolia Autonomous Region. The scale of the map is 1:3000000. The descriptive datas of the map are water bearing rock group and its water rich degree, the mineralization degree of groundwater, representative water points and various boundaries,etc. On the top left of the map is a hydrogeological partition map of the scale of 1:9000000.
A Water-bearing Formation and Its Water-Rich Degree
(1) porous aquifer formation of loose rock
Highly water-rich；Water-rich；Moderately rich in water；Weak water-rich；Weak water-rich
(2) Clastic rock pore-fissure aquifer formation
Clastic rock aquifer formation；Water-rich；Moderately rich in water；Weak water-rich
(3) Fractured karst aquifer formations of carbonate rocks
Carbonate aquifer formation；Moderately rich in water；Weak water-rich
(4) Fractured aquifer formation of magmatic rocks
Aquifer Formation of Invasive Rocks (Weak Water-Rich)
Water-bearing formations of extrusive rocks (moderately water-rich and weakly water-rich)
(5) Fractured aquifer formation of metamorphic rocks
