In the map, we can see the map of hydrology and geology in Taiwan Province, China. The scale of the map is 1:750000. 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.
A Water-bearing Salt Formation and Its Water-Rich Degree
(1) Pore water-bearing salt formations of loose rocks
Highly water-rich
Water-rich

Weak water-rich
(4) Fractured water formation of metamorphic rocks
Aquifer Formation of Metamorphic Rocks
Weak water-rich
Second Groundwater Burial Depth
Numerical value of groundwater burial depth (m)
Three Generations of Surface Water Points
Drilling machine number
Self-flowing Drilling and Numbering
Rising Spring and Number

Faults and inferred faults
Note: The mineralization degree of groundwater is mainly less than 1 g/liter except for the western coastal areas of Jipenghu Islands.
