The correlation between δD and H_2O content in granitoid can be divided into threetypes: closed-system crystallization type (Darongshan type): a flat positive linear corre-lation; open-system degassing type (Laoshan type): a nearly vertical linear positive cor-relation; meteoric hydrothermal exchange type (Gabug type): an irregular negative trendcorrelation.
