AXINITE (Fe) CHANGING COLOR. 2.97 cts. SI1. France
N / A

The + of this product

The structure of axinite consists of [Si4O12]8- rings and BO3 units; separate rings, parallel to each other and almost parallel to the (010) plane. These groups are linked by iron in octahedral position, by aluminum in tetrahedral and octahedral coordination, and by calcium which is located in the center of an irregular polyhedron of 10 oxygens.
Axinite appears as a mineral of contact metamorphism and metasomatosis. It is found in altered calcareous sediments and in altered basic igneous rocks undergoing metamorphism with the introduction of boron. It can be associated with other silicates rich in calcium and boron: tourmaline, datolite, calcic amphiboles, actinolite, zoisite, calcite, as well as quartz. Axinite is found in crystalline shales metamorphosed by granite. It is used as a gemstone
