Sorption of biotite

Forschungszentrum Karlsruhe. Wissenschaftliche Berichte, 2009
Gneissic rock types are common in the coastal regions of the Baltic Sea and in the area of the planned deep repository at Olkiluoto. Based on experimental data and molecular modelling of mineral surfaces, the chemical reactions governing the sorption of Ni(II) and Eu(III) were interpreted using well-established thermodynamic sorption models.

Chlorine, titanium and barium-rich biotites: factors controlling biotite composition and the implications for garnet-biotite geothermometry

Contributions to Mineralogy and Petrology, 1995
Barium-, Cl- and Ti-rich biotite occurs together with garnet, plagioclase and amphibole within narrow shear zones in 1800 Ma old noritic granulites in the Flakstadoy Basic Complex, Lofoten, north Norway. The granulite facies assemblage, plagioclase, clinopyroxene, orthopyroxene, biotite and ilmenite, was replaced by an amphibolite facies mineral ...

Stability of phengite and biotite in eclogites and characteristics of biotite- or orthopyroxene-bearing eclogites

Contributions to Mineralogy and Petrology, 2003
Stability of phengite and biotite in eclogite is discussed using petrological data of natural eclogites, and the observational data are examined by thermodynamic calculations. Generally, phengite is a major K phase in natural eclogite and is stable in wide range of bulk composition.

The biotite-prehnite association

Lithos, 1975
Abstract Prehnite interleaved with biotite in altered diorite from S.E. Queensland and elsewhere has a lens-shaped form which bows the enclosing mica cleavages. Despite the first description of the texture in 1918 and identification of the prehnite in 1936 only a few references to the intergrowth can be found. Genetic considerations usually involve K

The decomposition of biotite in the soil

Mineralogical Magazine and Journal of the Mineralogical Society, 1949
A noticeable feature of many of the soils of north-east Scotland is the presence in them of glistening yellow flakes of decomposed biotite. The light-reflecting property of this material catches the eye even though the flakes themselves are often of very small size.An analogous process to the breakdown of biotite as reported below occurs in the soil ...

Biotite from rapakivi

Mineralogy and Petrology, 1994
This paper deals with the chemical composition of biotites from rapakivi granites. For this purpose, 61 chemical analyses of biotites from composite anorthosite-rapakivi plutons in the Fennoscandian and Ukranian shields were used. Figurative points of the biotite composition were plotted on diagrams designed for biotites byFoster (1960),Winchell (1949)
