Fluorescent Zircon Crystals in Biotite Schist and Magnetite

This beautiful specimen contains deep red-brown zircon crystals that are still partially embedded in the biotite (mica schist) and magnetite matrix that they formed within. It was collected from Finnmark, Norway and the largest crystal measures .9" wide. Under short-wave UV the zircon fluoresces a stunning yellow color!

Biotite Mica Schist: Rockhounds Guide to Different Types

Biotite Schist and Granite Gneiss are two fine examples of metamorphic rocks that show foliated characteristics. Nonfoliate metamorphic rocks naturally lack foliated textures because they typically lack platy minerals like Mica. These types of stones commonly result from contact or regional metamorphism. Some examples of nonfoliate metamorphic ...

The composition of metapelitic biotite, white mica, and …

Abstract. Biotite, white mica, and chlorite record petrological processes and pressure–temperature conditions. Unfortunately, their crystal chemistry is complicated and thermodynamic modelling of their phase relations is hindered by this complexity. This article reviews the main atomic substitutions in metapelitic biotite, white mica, and chlorite and their relevance to mixing …
