| 1. | Sapphire from shandon and hainan commonly have the reaction border , we found out this reaction border enriched with fe , mg , and k by testing its components ; we also studied the inclusion in the sapphire , and found many kc1 crystal grain with variety of size , a melt inclusion enriched with k , si , is also found , this may suggest an assimilationary - magmatic course ; besides that , another minerl inclusions such as enstenite , magnetite , chromite , zircon are also found
3 、观察到了山东、海南蓝宝石普遍存在的反应边，并测试了反应边的成分，证实其以富fe ， mg ，和k为特征；研究了蓝宝石里面的包体，发现蓝宝石里面存在着大小不等的kcl的结晶颗粒，还发现了富k富si的熔浆包裹体，说明其形成过程中有同化混染的贡献；此外还发现了斜方辉石，磁铁矿，铬铁矿，锆石的包体矿物。 |
