The main mineral compositions of the tilting defect are composed of calcium aluminate and gehlenite,and others are zirconia corudu...

聚集的大型夹杂物与下水口侵蚀后的脱落物有。

Depending on the chemical composition the structural parameters of the melilite vary in the range between gehlenite and mernite.Melilitic separation and melilite as a primary phase are very rare.

石的结构数，按其化是在钙铝石和镁石之间变化，石作为原始矿物相在碱性矿渣中比较罕见。
