分析山东昌乐与碱性玄武岩有关的刚玉巨晶不同部位的常量元素、稀土元素及包裹体组成 .刚玉巨晶的主体以大量流体—熔体包裹体、锆石、铌 (钽 )铁矿包裹体为主 ,而巨晶中的“晶核”部位则以大量的熔体包裹体为主 ,反映研究区的刚玉巨晶是在不同的阶段形成的 .刚玉“晶核”以及“铜皮刚玉”形成于熔体相为主的体系中 ,而主体刚玉则形成于熔体—流体过渡的急剧变化的不均一的地球化学环境中 .
The Changle element of Shandong Changle is related to alkaline basalts, and is composed of major elements, rare earth elements and inclusions in different parts of corundum macroscopies. The main body of corundum macrocrystal is surrounded by a large amount of fluid-melt inclusions, zircon and niobium (tantalum) While the “crystal nucleus” in giant crystal is dominated by a large amount of melt inclusions, which reflects the formation of corundum giant crystals at different stages in the study area. "Is formed in the melt-dominated system, while the host corundum is formed in a heterogeneous geochemical environment with a drastic change in melt-fluid transition.
