Kyanite - Wikipedia

Kyanite is the triclinic polymorph of aluminosilicate minerals with the formula Al 2 SiO 5 - two others being andalusite and sillimanite. Kyanite belongs to the nesosilicates, which have isolated SiO 4 tetrahedra. Most often, it occurs in long, slender groups of bladed crystals that can appear prismatic, radiating or reticulated.

Andalusite, Kyanite, and Sillimanite from the Mount

Kyanite appears once in the same thin section with sillimanite but never with andalusite. Andalusite and sillimanite mica schists were subjected to multiple episodes of recrystallization that resulted in the reaction sequence andalusite → sillimanite → andalusite. Kyanite crystallized in an adjacent area during the same time period.

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 …
