Kyanite

Kyanite is a blue aluminosilicate mineral that forms distinctive elongate crystals. It found in metamorphic rocks, pegmatite intrusions, quartz veins, and rarely in sedimentary rocks. It forms under high pressure metamorphic conditions. In fact, geologists use it as an indicator of the metamorphic conditions that affected a rock, since it only forms under particular pressure and temperature conditions. Kyanite has the unusual property of anisotropic hardness. That means that its hardness is different in one orientation to another; its hardness along its long axis is different to its hardness across it. Kyanite is used mainly in ceramics and electronics.

This sample is from Enderby in the Southern Interior region of BC.

It was collected from one of eight claims south of Enderby staked in the 1950s when logging exposed an outcrop containing quartz-kyanite veins. The veins are up to 2 metres wide in metamorphic schist host rocks.
