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
分析山東昌樂與堿性玄武巖有關的剛玉巨晶不同部位的常量元素、稀土元素及包裹體組成.剛玉巨晶的主體以大量流體?熔體包裹體、鋯石、鈮（鉭）鐵礦包裹體為主，而巨晶中的「晶核」部位則以大量的熔體包裹體為主，反映研究區的剛玉巨晶是在不同的階段形成的.剛玉「晶核」以及「銅皮剛玉」形成於熔體相為主的體系中，而主體剛玉則形成於熔體?流體過渡的急劇變化的不均一的地球化學環境中The dwelling zone is followed by a vertical return pin chain / stenter section, where the fabric is uniformly stretched during the gradual removal of the caustic content
