영문 초록

Carbonated mineral waters fo Ca(Mg)-HCO3 type spring out fissure of Jurassic granite in the valley floor of the Chungsong area. The water has been long as a Dalki medicinal water because of its unique therapeutic effect against clacium deficit, stomach and skin troubles, ect. The water has a high CO2 concentration (Pco2=0.51∼1.12atm) and exhibits strong pH buffering (5.9∼6.26) by H2CO3/HCO3 couple. Electrical conductivity ranges from 1,900 to 3100 μS/cm. Environmental isotopic data (2H/1H, 18O/16O and 3H) indicates that the water is of meteoric origin recharged in the Cretaceous sedimetary strata distributed in upper part of the catchment area at least before 1950s, The high Pco2 and carbon isotope data (δ13C=-3∼0.2‰) suggest that the potential source of carbonated mineral water was originated in deep-seated CO2 as wel as aboundant carbonate minerals of sedimentary desimetary rocks. The major source minerals of the dissoved species in the carbonated mineral water appear to be carbonate minerals, albite and K-feld-spar in sedimentrary rocks.
