The structure model of fibrous amosite (fibre_T). (a) Projection along a, (b) projection along b and (c) projection along c. Legend: blue polyhedra = tetrahedral centred by Si, blue balls = Si atoms, green balls = F atoms, red balls = O atoms, purple balls = Mg atoms, yellow balls = Ca atoms, light blue balls = F substituting O atoms. The dotted line circles are used to better illustrate the amphibole sites (Hawthorne, 1983
