Crevice water in the Panshan granite originates from meteoric water. It occurs in fissures of various origins. The age of crevice water is very different, varying from less than 4 years old to about 40 years old. The common elements and trace elements in crevice water are mainly derived from hydrolysis of feldspars, especially anorthite. The contents of SiO2 and Sr in crevice water are relatively high and have met the standards of drinking mineral water. The amount of minable crevice water resources is 12. 9156 million m3/a on average. The regularity of crevice water yield is clear.
