'''المايونيت''' (Meionite) عبارة عن [[معدن]] سيليكات ينتمي إلى مجموعة ال[[سكابولايت]] [[صيغة كيميائية|صيغته]] Ca<sub>4</sub>Al<sub>6</sub>Si<sub>6</sub>O<sub>24</sub>CO<sub>3</sub> . بعض الأمثلة قد تحتوي أيضاً على مجموعة كبريتات . اكُتشف لأول مرة في عام 1801 م على جبل سوما، [[جبل فيزوف|فيزوف]] ، [[إيطاليا]] .
