| Abstract | Water samples taken from 4 geothermal wells and 3 springs in Kangding’s county geothermal fields, are examined in this paper.The sacling trend of the thermal groundwater is calculated and judged by the methods of Ruzner,s index and larson,s index , the WATCH program and Na–K–Mg equilibrium diagram. The results show that thermal groundwater in part of the geothermal wells and springs in Kangding areas has a tendency to scale.The main precipitated scaling matter is CaCO3.And Chrysotile,Calcite and Talc are responsible for the scaling. |
