2023.3.21 Staurolite can be formed as a secondary mineral in high-pressure mineral assemblages of metabasites and replace chloritoid, corundum, and/or the garnet–kyanite assemblage. The mineral is also found as small inclusions in garnet (e.g., Enami and
More2021.7.23 Abstract. Staurolite stability in rocks of zonal metamorphic complexes and the subsequent decomposition of this mineral in the rocks at increasing temperature is a criterion for distinguishing the staurolite metamorphic zone. Along with other metamorphic zones, this zone reflects the temperature distribution configuration when the metamorphic ...
More2003.10.1 INTRODUCTION. Staurolite-bearing mineral assemblages are characteristic of medium-grade metapelites, but are scarce at higher grade (Pattison Tracy, 1991).The rare cases in which staurolite appears to be stable at high grade are explained in terms of the enhancement of its stability as a result of the lack of quartz
MoreFormula: Fe2+2Al9Si4O23(OH) The formula can also be considered as alternating layers of kyanite and oxide, and so can be recast as: 4Al 2 O [SiO 4]. AlFe 2+2 O 4 H. Colour: Dark brown, brownish-black, red-brown. Lustre: Sub-Vitreous, Resinous. Hardness: 7 - 7½. Specific Gravity: 3.74 - 3.83. Crystal System: Monoclinic. Member of:
MoreAbstract. Previous studies of staurolite have suffered from inadequate knowledge of its chemistry, crystal chemistry, and the relation of these to petrologic occurrence. We provide complete analyses of 31 metapelitic staurolites in an
MoreSummary. The history of staurolite (1792-present) demonstrates how long it takes for superseded teachings to be discarded in favor of new results, witness the long estrangement of X-ray crystallographers from morphological mineralogists. The first staurolite structure was described in Ccmm (Náray-Szabó, 1929).
More2023.5.14 Staurolite is a metamorphic mineral that forms under high temperatures and pressures. It is known for its distinct cruciform or cross-shaped crystal habit. How does staurolite form? Staurolite forms during
More1997.8.1 Abstract. The Fe Mg exchange between synthetic staurolite and garnet was determined experimentally as a function of pressure, temperature and bulk composition in the range of 5–25 kbar/600–750°C on the basis of the reaction 1 2 pyrope + 1 4 Fe-staurolite = 1 3 almandine + 1 4 Mg-staurolite (Eq. (1)).
More2024.1.4 Staurolite is monoclinic with p = 90o, and also (a) pseudo-orthorhombic. Its composition is not particu-larly complicated, but recent confirmation that both H

More2024.5.15 La Staurolite è nota anche come "pietra della croce" a causa della sua forma peculiare che richiama una croce. Questo minerale si trova spesso in forma grezza ma può essere anche lavorato per creare splendidi gioielli. In cristalloterapia, la Staurolite è utilizzata per le sue proprietà calmanti ed equilibranti.

More2023.5.14 La staurolite est un minéral métamorphique qui se forme sous des températures et des pressions élevées. Il est généralement associé à des roches métamorphiques de qualité moyenne à élevée. Il se caractérise par son port cristallin cruciforme ou en forme de croix distinct, résultat d'un jumelage.

More2023.5.14 Staurolite is a mineral that is known for its unique crystal shape and its association with metamorphic rocks. The name "staurolite" comes from the Greek words "stauros" meaning "cross" and "lithos" meaning "stone," referring to the characteristic cruciform or cross-shaped crystals that can be found in some specimens. These
More2022.8.29 The occasionally used name “Fairy Cross” is quite accurate, as the twinned crystals often form at distinct right angles ot each other. This creates a cross that can be seen in most specimens of the mineral. Staurolite itself is a simple mineral. It has a hardness of 7.0 on the Moh’s scale and is usually a reddish-brown to black color ...
