About IlyukhiniteHide

Specific Gravity:
Crystal System:
Member of:
Named in memory of the outstanding Russian crystallographer Vladimir Valentinovich Ilyukhin (Владимире Валентиновиче Илюхине) (1934-1982).
The second hydronium-dominant member after aqualite, also characterized in predominance of Mn over Fe (the M2 position, the Mn located in the centre of tetragonal pyramid). Chemically somewhat similar to manganoeudialyte and låvenite.
