...Marcello Mellini Abstract The occurence of lizardite 1 T from Val Sissone, Italy, is reported. Electron microprobe analysis leads to the doubled unit cell content ( Mg 5.58 Fe 0.08 2 + Fe 0.20 3 + Al 0.14 ) ( Si 3.66 Al 0.34 ) O 10.00 ( OH ) 8.00 . The unit cell parameters are a = 5.332(3)Å, c...

..., this assignment of the OH stretching modes in serpentine minerals is consistent with structural refinements of lizardite-1 T from Val Sissone ( Gregorkiewitz et al. 1996 ; Mellini and Viti 1994 ) showing that the inner O4-H4 bond (~0.80 Å) is significantly shorter than outer O3-H3 bond (~1.16 Å). Consequently...
