Abstract
Electron microprobe analysis suggests a doubled unit cell of 298(Mg (sub 5.58) Fe (super 2+) (sub 0.08) Fe (super 3+) (sub 0.20) Al (sub 0.14) )(Si (sub 3.66) Al (sub 0.34) )O (sub 10) (OH) (sub 8) . The unit cell has a 5.332, c 7.233 A; space group P31m. The 6-membered ring distortion is small (alpha = -3.5 degrees ) and there is no buckling of the brucite sheet. The substitution of Mg and Si promotes stronger H bonds and therefore a flat layer structure with a higher thermal stability. The lizardite is from Val Sissone, Italy.
