This beautiful specimen contains deep red zircon crystals that are still partially embedded in the biotite (mica schist) and feldspar matrix that they formed within. It was collected from Finnmark, Norway and the largest crystal measures .8" wide. Under short-wave UV the zircon fluoresces a stunning yellow color!

the octahedral Al-content predicted for KFMASH-biotite compared to Bi(W). Whereas in both models the ferric biotite end-member fbio is formulated identically, the recalibration of T09 is based on a dierently dened Ti-biotite end-member tbio, with Ti replacing Mg on the M2 position and deprotonation of the hydroxyl site to achieve charge balance.

Based upon petrographic characteristics, back-scattered electron images, and compositional attributes, biotite from the Sungun Porphyry copper-molybdenum deposit was grouped into least-altered magmatic biotite (LA-Mbt), least-altered equilibrated magmatic biotite (LA-Eq Mbt), equilibrated magmatic biotite (Eq-Mbt), and secondary hydrothermal ...

A new mineral standard for K-Ar dating, SORI93 biotite, has been prepared from the Sori Granodiorite in Gunma Prefecture, Japan. This is intended as a substitute of the existing standard, SORI biotite, which is well calibrated against international standards.

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 …
