【Abstract】 The hydrochemical types and distribution of waters in the Wudalianchi volcanic area were discussed based on a lot of hydrochemical data. Deep ground water in cryst alizing rocks has higher mineralization and is rich in HCO3,SO24 and Cl. The source areas of the ground water are located in the north part and central part of the study district.更多还原
