About SepioliteHide

Formula:
Mg4(Si6O15)(OH)2 · 6H2O
Colour:
White, light gray or light yellow.
Lustre:
Sub-Vitreous, Silky, Dull, Earthy
Hardness:
2
Specific Gravity:
2.0 - 2.2
Crystal System:
Orthorhombic
Member of:
Name:
Named in 1847 by Ernst Friedrich Glocker from the Greek, "sepion," cuttle-fish bone, because of its low density and porous, bone like appearance. Originally named meerschaum by Abrahan Gottlieb Werner in 1788. Later translated as l'Ecume de mer. In 1794, the mineral was called keffekill by Richard Kirwan. Alexandre Brongniart called this mineral magnesite in 1807.
Isostructural with:
Commonly found as compact masses of microscopic needles resulting in a low-density masses. May be an important constituent of "mountain leather". Free-standing acicular crystals not found in many localities.

May be confused with palygorskite. Results of García-Romero & Suárez (2010) indicate that no compositional gap exists between sepiolite and palygorskite.
