The crystal structure of two different crystals (Fa(39)Fo(11)La(50) and Fa(35)Fo(14)La(51), respectively) are refined (orthorhombic unit cell parameters: a = 4.877 and 4.875, b = 11.166 and 11.164, c = 6.448 and 6.447 Angstrom), yielding similar results. In particular, the geometry of the M2 and T coordination polyhedra does not change with respect to other calcium bearing olivines, whereas M1 is sensitive to the site population.

Abstract
The crystal structure of two different crystals (Fa(39)Fo(11)La(50) and Fa(35)Fo(14)La(51), respectively) are refined (orthorhombic unit cell parameters: a = 4.877 and 4.875, b = 11.166 and 11.164, c = 6.448 and 6.447 Angstrom), yielding similar results. In particular, the geometry of the M2 and T coordination polyhedra does not change with respect to other calcium bearing olivines, whereas M1 is sensitive to the site population.File in questo prodotto:
