山东蓝宝石原生矿研究

STUDY OF THE PRIMARY ORIBODIES OF SAPPHIRE IN SHANDONG PROVINCE

山东蓝宝石原生矿的形成与第三纪火山活动密切相关 ,其形成方式有两种 :① 在火山活动中 ,玄武质岩浆捕虏先前形成的蓝宝石并将其带至地表 ;② 在玄武岩形成过程中分异结晶而成 .含矿橄榄玄武岩和碧玄岩含大量深源包体和巨晶矿物 .

The formation of the primary sapphires is related to the volcano activities in tertiary period.Their formation has two types:① in the process of the volcano activities,the basaltic magma carried the sapphires that had formed before to the earth's surface;② in the process of the basaltic rocks forming,the sapphires crystallized from the basaltic magma.The olivine basalts and basanites,with a great deal of xenoliths and megacrystalline minerals,contain the original sapphires.
