Kyanite: The blue mineral kyanite information and pictures

Kyanite is strongly anisotropic, meaning it has a different hardness depending on the angle.In fact, it is the most well-known anisotropic mineral. The vertical hardness of Kyanite ranges from 4.5 to 5.5, and horizontal hardness from 6 to 7.

Kyanite Mineral Uses and Properties

FormationCharacteristicsCompositionUseIndustryOther usesPropertiesSignificanceAppearanceKyanite is a mineral found mainly in metamorphic rocks. It most often forms from the high-pressure alteration of clay minerals during the metamorphism of sedimentary rocks. It is found in the schists and gneisses of regionally metamorphosed areas and less often in quartzite or eclogite.

Kyanite mineral Britannica

Kyanite, also spelled cyanite, also called disthene, silicate mineral that is formed during the regional metamorphism of clay-rich sediments. It is an indicator of deep burial of a terrain. Kyanite occurs as elongated blades principally in gneisses and schists, and it is often accompanied by garnet, quartz, and mica.It can also occur in igneous rocks such as granite.

Metamorphic and Metasomatic Kyanite-Bearing Mineral

The paragneisses/mica schists mainly show a sub-horizontal (azimuth N140-300, dip up to 20° W) S n foliation, bearing kyanite mineral lineation, oriented N255 ± 15°, and gently dipping to the WSW. Late brittle deformation is evidenced by tension gashes that cross-cut S n. These veins are oriented N330 ± 15° and are generally close to vertical.

Discovery of kyanite in typically cordierite/sillimanite

Jun 15, 2020In this study, we identify kyanite relics and the mineral assemblage of kyanite + K-feldspar + rutile + garnet from typical cordierite/sillimanite-bearing LMP pelitic granulites. Integrated approaches of petrology, phase modeling, and geothermobarometry reveal an earlier HP granulite-facies metamorphism, with minimum P-T conditions of 860–870

The prism faces of kyanite exhibit an unusual phenomenon also. Two of the narrow faces are striated vertically, and horizontal striations appear on the broad cleavage face. A plane of perfect parting oblique to the length of the crystal causes tiny horizontal cracks visible on the face. Kyanite is very brittle.

Kyanite has variable hardness, which depends on how its cut. If the stone is cut along its horizontal axis, the Mohs hardness ranges from 4 to 4.5, making it quite fragile. However, if cut in the opposite direction, along its perpendicular axis, the hardness ranges from 6 to 7 on the Mohs scale. Kyanite Color
