Notes
(Richard Willis)
Mineral, of the ideal form Mg4[(OH)2Si6O15] 2H2O+4H2O with a typical empirical analysis of MgO 24.88%, SiO2 55.65%, H2O 19.47%
Hardness: 2-2.5 Density: 2 Soluble in HCl
Formed in ocean floors, usually accompanying palygorskite as a palygorskite-sepiolite feldspathic earth. The earth behaves similarly to granite and volcanic feldspars high in alkalies and iron but is much more light and porous. Both palygorskite and sepiolite float in water.
