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

聚集的大型夹杂与下水口侵蚀后的脱落有。

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.

长石的结构参数，按其化学成分是在钙铝长石和镁长石之间变化，长石作为原相在碱性渣中比较罕见。
