In the map, we can see the map of hydrological and geological maps of Sichuan Province, China. 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.

1.Aquiferous rock group and its water richness

(1) Loose rock-like interstitial water-bearing rock group

(2) Clastic rock voids and water-bearing rock group:

①Clastic rock pore fracture water-bearing rock group

②Clastic rock type carbonate rock type water rock group

(3) Carbonate rock fracture karst aquifer group:

①Carbonate-bearing aquifer

②Carbonate-like clastic rock-like aquifer

③Carbonate rock eruption rock type aquifer group

(4) Magmatic rock fractured water-bearing rock group:

①Intrusive rock aquifer
