Staurolite: The mineral staurolite information and pictures
The Mineral staurolite Staurolite is best known for its distinctive, cross-shaped penetration twin s, where two rectangular crystals intersect each other to form a perfect cross. However, its most common twinning habit is in bisecting crystals with a 60° angle that can appear

Staurolite thin section - Nesosilicates - MicROCKScopic
Staurolite is a metamorphic mineral that is found almost exclusively in medium-grade schists. In general, it has an isolated tetrahedral structure related to that of kyanite. The name comes from the Greek for cross, in allusion to its common cruciform twins.
ALEX STREKEISEN-Staurolite-
Staurolite - (Fe 2+,Mg,Zn) 2 (Al,Fe 3+,Ti) 9 O 6 [(Si,Al)O 4] 4 (O,OH) 2 The name "staurolite" is from the Greek word "stauros" which means "cross". The mineral commonly occurs as twinned, six-sided crystals that sometimes intersect at 90 degrees to form a cross (an intersection angle of 60 degrees is more common). In some localities these twinned crystals are collected, made into jewelry, and ...
Staurolite - an overview ScienceDirect Topics
Staurolite is affected by retrograde metamorphism, resulting in it being mantled and partially replaced by chlorite. Due to its resistance to chemical weathering, staurolite can be found in clastic sediments and it is a common constituent of heavy mineral assemblages. At deeper levels in the crust and at higher pressures, chlorite breaks down to form staurolite instead of cordierite over a ...

Staurolite – Tronox
Staurolite is a relatively hard, inert mineral with similar properties to garnet, making it suitable as an abrasive sand blasting media. In this application, it is directed at a metal surface using compressed air through a nozzle, so that the grains of staurolite cut through and remove any paint, rust or other residual coatings. The cleaned surface is then ready for painting or welding as part ...

KYANITE - STAUROLITE
Kyanite and staurolite are two silicate minerals which are structurally closely related. Staurolite can be viewed as kyanite (AlrSiOr) with inserted layers which contain Fe in tetrahedral sites and have a composition AIO-OH-2FeO (Fig. l). The interface is nearly coherent, with (010) of staurolite corre-sponding to (100) of kyanite (Naray-Szabo, 1929; Naray-Szabo et al., 1929; Burnham, 1963 ...

Recently, extraction and enhancement of the quality of concentrates (Rutile, Staurolite, Ilmenite, Zircon and Distan-Silanite) has been considerably increased at the Vilnogirsk Mining and Metallurgical Combine (Dnipropetrovsk
Biasill™ Staurolite Chemours Mineral Solutions
Biasill™ staurolite sands have a slightly finer grade than the coarser blasting abrasives offered, such as Starblast™ Ultra. This finer grit enables Biasill™ staurolite sand to be used on softer substrates, including aluminum, composites, and fiberglass. Biasill™ blasting abrasive is certified by the California Air Resources Board (CARB).
