摘　　要：Mixing processes are universal in the genesis of thermal waters from Xinzhou basin. Chemical and isotopic (δD-δ18O,34S/32S,87Sr/86Sr,T) data are comprehensively used to dis cern the geochemical and hydrodynamic environments of these waters. Based on a two-year hydrochemical monitoring on thermal waters from the well XD1 in Duncun geothermal field . a series of changes in quality have been observed , which are attributed to the change in the proportion of end members making up the thermal waters being withdrawn .Mixing processes are universal in the genesis of thermal waters from Xinzhou basin.
