CHARACTER OF THE CREVICE-WATER CHEMISTRY IN THE PANSHAN GRANITE

The weathering crevices and tectonic crevices are developed well in Panshan granite.The crevices direction is NE45°-65°and NW310°-340°. Ground water is stored in all kinds of the granite crevices and getes elements from rock.The common elements of the granite crevice-water in Panshan are K+, Na+ , Ca2+, Mg2+, CI-, SO42-, HCO3-, SiO2 ect. and the trace elements are Sr2+, Li+, F-ect..Their average content is showed in table 1. Specially in the fault tectonic,the type of water chemistry is H. S-N which is different from other and the contains of trace element Li+ , Sr2+ , F- is higher.
