Kyanite is a typically blue aluminosilicate mineral, found in aluminium -rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite, and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust. Kyanite is also known as disthene or cyanite. [5]

Kyanite 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 …

Kyanite is an aluminum silicate mineral, often occurring as long, striated bladed crystals that may be transparent or translucent with a pearly sheen. The most common colors in metaphysical use are blue streaked with white, indigo, green, and black, though Kyanite may occur in white, gray, pink, yellow, and most recently discovered orange.

2023年10月25日 · Kyanite is a mineral composed of aluminum silicate, and it belongs to the family of aluminosilicate minerals. Its chemical formula is Al2SiO5. Kyanite typically forms bladed crystals, and its name is derived from the Greek word “kuanos,” meaning blue, which reflects its most common blue coloration.

2024年3月8日 · 蓝晶石英文学名「Kyanit」是源自希腊文，原意为蓝色。 蓝晶石是典型的区域变质矿物，主要形成于低温高压的变质岩相。 属三斜晶系，晶型多呈扁平状的柱状晶体，晶面上有平行条纹，在鉴定上通常有色带现象。

2024年9月11日 · Kyanite is an aluminum silicate mineral that's notoriously difficult to facet because of its perfect cleavage and variable hardness, even within the same crystal. When cut parallel to its (long) c-axis, it has a hardness of 4 to 4.5. When cut perpendicular to its c-axis, it has a hardness of 6 to 7.5.

kyanite，英语单词，主要用作名词，作名词时译为“ [矿物] 蓝晶石”。

Kyanite is one of the most attractive blue minerals in nature. It sometimes exhibits intense shades of blue, or even multiple shades with color zoning in a single crystal. The color of Kyanite, combined with its well-formed and sometimes large crystals, make this mineral appreciated by both novice and expert collectors alike.

kyanite, 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.
