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.

主要集中于伟晶质脉体和花岗岩中，是这期岩浆冷凝过程析出的流体相当时就被封闭所成，密度为0.93～0.96g/cm3，相应压力约0.6GPa，这与峰期后迅速减压过程结束时的条件相符。3CO2-H2O两相和多相包体，分布最广，成簇状和拖尾状包体群，碳质和H2O相对含量很不均匀，整体密度相对最低，一般为0.6～0.8g/cm3，相应压力为0.3～0.4GPa，它们可能是大幅度减压过程中第一类包体大量爆裂析出的碳质流体与第二类H2O溶液流体在各处以不同比例混溶所成，它们被封闭后在降温至330℃以下时分裂成两相或三相包体。
