They are most abundant in quartz of pegmatitic leucosomes and granitic rocks, and represent the fluid appearing in their cooling stage. The DL(H2O) of such fluid is 0.93~0.96g/cm3 corresponding to P≈0.6GPa which is compatible with condition when the rapid decompression in this region was ended. 3 CO2-H2O two or three phases inclusions. They are the most widespread, and more frequently in clusters and in intragranular tails in quartz. The relative content of CO2+CH4 and H2O is considerably variable. They are also characterized with lower density (0.6~0.8g/cm3) and low pressure about 0.3~0.4GPa, and may be originated by mixture of carbonic liquid from breaking of most inclusions of peak stage and aqueous liquid of magmatic source. After entrapment, the further decrease of temperature to lower than 330℃ made such fluid separated to two or three phases.
