The Ningzhen granitic body is situated between Nanjing and Zhenjiang, formed in the Late Yanshanian period and belongs genetically to syntectic granitoids. Its major rock types are granodiorite porphyry, granodiorite, quartz diorite-porphyry and so on. This paper deals with the magmatic inclu- sions developed in two dark dikes-olivine gabbro dike and monchiquite dike intruding into the granitic body. These inclusions are enclosed in clino-pyro- xene and olivine phenocrysts. Most of them are well-developed primary mag- matic inclusions of evolution type, consisting of daughter minerals such as pyroxene, ilmenite, biotite and potassium feldspar. Some CO2 fluid inclusions are also observed. The homogenized temperatures of the magmatic inclusions are between 1220-1270℃. The results of electron microprobe analyses of homo- genized inclusions indicate that magmas trapped in the early crystallized pyroxene phenocrysts are evidently more acidic than host rocks. Combined with other evidences it suggests liquid immiscibility took place during the formation of the dikes, thus providing an evidence for the hypothesis of la- yered magma chamber to explain reversed magmatic activity.
