The chemical composition of several thermal springs around Changbaishan area has been investigated.Cenozoic basaltic rocks are widely distributed in Northeast China and geothermal characteristics have been described.About one hundred hot springs exist around Changbaishan Volcano at the border between China and D.P.R.Korea with high temperature about 82℃. The pH values of the spring water range from 6.9 to 7.1 and the total flow rate is about 4.8 L /sec. The chemical composition of the thermal springs is sodium carbonate; the high-mineral contents of thermal water are believed to have medicinal properties. Bathhouses are already built along the hot springs to take the advantage of the supposed healing properties. The high quality of those hot springs is believed to be utilitized for mineral water. The chemical equilibrium temperatures were estimated at about 160℃ based on the Na-K-Ca geochemical thermometer.
