Orthopyroxene-sillimanite granulites of the Angara-Kan block

Mar 01, 2021 · The Kan granulite-gneiss complex consists of metamagmatic and metasedimentary rock associations (Nozhkin and Turkina, 1993). The predominant metasedimentary association is composed of garnet-bearing, garnet-orthopyroxene and orthopyroxene-bearing gneisses, and high-Al gneisses with cordierite and sillimanite.

Sillimanite Gemstone Information - GemSelect

Jul 29, 2015 · Sillimanite is composed of aluminum silicate, which is a polymorph; sillimanite, kyanite and andalusite all share the same chemical composition (Al2SiO5), but each exhibit differing unique crystal structures. Sillimanite forms as orthorhombic, hexagonal crystals, whereas kyanite and andalusite crystals are both formed as triclinic crystals.

Sillimanite biotite hornfels | Virtual Microscope

Blades of sillimanite are present in some bands. The thin section also contains excellent examples of the rare mineral jimthompsonite, which appears to have replaced (pseudomorphed) earlier porphyroblast mineral in this rock. Jimthompsonite is a pyribole, with a structure similar to micas and amphiboles.

Sillimanite | mineral | Britannica

Sillimanite, brown, pale green, or white glassy silicate mineral that often occurs in long, slender, needlelike crystals frequently found in fibrous aggregates. An aluminum silicate, Al2OSiO4, it occurs in high-temperature regionally metamorphosed clay-rich rocks (e.g., schists and gneisses).

Garnet sillimanite gneiss - Isle of Harris | Virtual Microscope

In thin section the coarse-grained texture is dominated by two types of layer. The first layer type is composed of garnet (slightly lower relief and isotropic) and coarse-grained sillimanite (slightly lower relief and medium birefringence colours). The remainder of the rock is a finer-grained matrix of quartz, biotite and feldspars.
