The compositions of usual elements and rare earth elements and inclusions of corundum megacrysts related to alkali basalt in changle, shandong province, are analyzed. in the main parts of corundum megacrysts are a large number of fluid - melting inclusions, zircon, ta - columbite inclusions, and in the central crystal core are a large number of melting inclusions. the corundum megacrysts were formed in different periods and different physical chemistry conditions. the crystal core was formed in magma system, and the main parts were formed in inhomogeneously geochemical conditions in which magam and fluid phases coexisted
