Abstract

Antigorite from Stragari asbestos deposit is light green, lath-shaped mineral, found in serpentinite fractures. The examined massive specimen has relatively homogenous textural fabric of a marked preferential micro-crystals orientation, as observed by optical and X-ray examinations. Structural features have been determined from X-ray data, by the indexing method after Uehara & Shirozu (1985), and are the following:

a=5.415(3) Å, b=9.238(3) Å, c=7.288(3) Å, β=91.2°(1), v=364.5 Å3 and M=7.91(8)

IR spectrum is typical of antigorite with an additional absorption band at 3400 cm-1, which reveals a cationic substitution in tetrahedral sheet. The chemical formula is:

(Mg5.84Fe3+0.14Fe2+0.11)6.09(Si4.06Al0.13)4.21O10.63(OH)7.75

The presence of antigorite is particularly important for the genetic concept of chrysotile asbestos at Stragari.
