摘要

Besides the solid rock xenoliths in basalt, writers found the glass xenoliths, which is different from both host basalt and solid rock xenoliths. Glass xenoliths consist mainly of K-riched nepheline crystals and glassand they are unequilibrium with the Na-riched host basalt magma, enhancing the K content of basalt.
