Sillimanite - an overview | ScienceDirect Topics

Depending on the P, T conditions, aluminosilicates Al 2 SiO 5 exhibit three polymorphs: andalusite, sillimanite, or kyanite (Fig. 7).The polymorphic transformations are sluggish because of the very low differences between their Gibbs free energies. All of the polymorphs share a common crystal structure, i.e., chains of AlO 6 edge-shared octahedra parallel to the c-crystallographic axis.

The four factors are temperature, lithostatic pressure, the amount of composition of fluids, and the composition of the parent rock. Briefly describe contact metamorphism and the conditions which cause it. Contact metamorphism is caused by heat from a magmatic intrusion. Rocks located close to the intrusion of magma will be highly metamorphosed.

Thermal expansion of the Al2SiO5 polymorphs, kyanite ...

Powder and single-crystal diffraction data measured from the three geologically important Al2SiO5 polymorphs, kyanite, andalusite and sillimanite, over the last six decades have given varying accounts of each polymorph's thermal expansion, the scatter between and even within experimental datasets often being quite large. Furthermore, there are no lattice parameter determinations below …
