[1C08] Theoretical estimation method of the groundwater chemistry in granite.

*Teruki Iwatsuki1, Hiroaki Murakami1 (1. JAEA)

Keywords:Granite, Groundwater, Chemical simulation, Long-term variation

We reproduced the groundwater quality in granite up to a depth of about 1000m using the geochemical simulation code, and devised a method to identify the major minerals involved in the evolution of water quality. We also estimated the long-term water-rock interaction of these minerals based on groundwater ages.
