Remarks：Cerasite is a pseudomorph of cordierite and indialite. A pseudomorph is a mineral that is altered by another mineral through a chemical process. The mineral retains it's orginal shape, but is replaced by a different mineral. In this case muscovite(mica) replaces the cordierite and indialite resulting in beautiful flower like patterns.
Name: named for 'ceras'=cherry blossoms.
Indialite + cordierite intergrowth of trapiche habit, named for its resemblance to flower petals. Generally altered largely or entitely to musocvite or "sericite"
