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 trace element contents follow a differentiation trend from the least to most evolved phases, indicative of a continuous magmatic evolutionary series. The fact that high degrees of fractional crystallization produced units Dmd2 and Dmd3 associated with endogranitic Sn, W (Mo), Bi, Zn and U mineralization is reflected in the composition ...

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 ...
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 …

The adsorption capacity of biotite for Cs + was calculated using Eq. (1). (1) Q = C 0 − C e V W where Q is the adsorption capacity of biotite for Cs + (mg Cs + /g), and C 0 and C e are the initial and equilibrium concentrations of Cs + in the solution after 48 h of contact time (mg/L), respectively; V is the Cs + solution (L) volume; and W is ...

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 ...
The chemical composition and charge of the biotite near-surface, in contact with NaCl bearing aqueous solutions at 25 °C from pH 1 to 12, have been derived via zeta potential measurements and potentiometric titrations performed for 20 and 60 min in batch reactors.Zeta potential measurements yielded an isoelectric point of pH 3.0 (±0.2) and batch potentiometric …
