An aluminosilicate mineral is a type of mineral that contains both aluminum and silicon in its chemical composition. Sillimanite(Al2SiO5)(Orthorhombic) Sillimanite is a high-temperature polymorph of Al2SiO5 and occurs as colourless or white acicular to fibrous crystals in high grade metamorphosed pelitic rocks. It has high relief and straight extinction. a 1.653—1.661 b 1.657—1.662 g 1.672—1.683

Garnet Group The minerals of the garnet group crystallize in the isometric system and belong to the Neso silicate group of silicates. General Formula X^{+2}_3 Y^{+3}_2 Z^{+4}_3O_{12} Where: X+2 = Ca, Mg, Fe, Mn (occupying dodecahedral sites) Y+3 = Fe, Al, Cr (occupying octahedral sites) Z+4 = Si, Ti (occupying tetrahedral sites) 1) Pyralspite Series

Olivine Group Introduction General Formula: R2SiO4, where R = Mg, Fe, Mn, & Ca. Structure The structure consists of independent SiO4 tetrahedra linked by divalent (Mg, Fe) atoms in octahedral coordination (each of which has six nearest oxygen neighbors). Octahedra in a structure are represented as (M): M1 < M2 < M3 < M4 Note:
