The stability of antigorite in subduction zones revisited: the effect of F on antigorite stability and its breakdown reactions at high pressures and high temperatures, with implications for the geochemical cycles of halogens
Autor: Stamatis Flemetakis, Carla Tiraboschi, Arno Rohrbach, Jasper Berndt, Stephan Klemme
Publikováno v: Contributions to Mineralogy and Petrology. 177
We present new experimental data on the effect of F on the stability of antigorite and its breakdown products at high pressures (2–6 GPa) and high temperatures (570–850 °C). The experiments show that F does not affect the stability of antigorite

The elemental and isotopic abundances of halogens (F, Cl, Br, I) are used to constrain planetary volatile loss and volatile delivery processes, but their behavior during magmatic differentiation in general, and sulfide liquid segregation in particula

The potential of phosphorus in clinopyroxene as a geospeedometer: Examples from mantle xenoliths
Autor: Stamatis Flemetakis, Stamatios Xydous, Stephan Klemme, Jasper Berndt, Constantinos Mavrogonatos, Ioannis Baziotis, Paul D. Asimow
Publikováno v: Geochimica et Cosmochimica Acta. 266:307-331
We investigate the potential to use concentrations and zoning patterns of phosphorus (P) in clinopyroxene as indicators of the rates of igneous and metasomatic processes, comparable to recent applications of P in olivine but applicable to more evolve

An Improved Electron Microprobe Method for the Analysis of Halogens in Natural Silicate Glasses
Autor: Anita Cadoux, Stamatis Flemetakis, Felix S. Genske, Jasper Berndt, Arno Rohrbach, Stephan Klemme, Marion Louvel
Publikováno v: Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada. 26(5)
We present a new analytical method, which allows the simultaneous analysis of fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) in geological samples. To account for interferences of Fe on the spectral lines of F, of Al on Br-lines, and of Ca

Phosphorus-rich olivines in a composite xenolith from Morocco: implications for growth processes
Autor: Stephan Klemme, Stamatis Xydous, Ioannis Baziotis, Paul D. Asimow, Angeliki Papoutsa, Stamatis Flemetakis, Jasper Berndt, Constantinos Mavrogonatos
Phosphorus(P)-rich zones in olivine may reflect incorporation of P in excess of equilibrium partitioning during rapid growth (e.g. Milman-Barris et al. 2008). We investigated (by optical microscopy and electron microprobe) a composite mantle xenolith

Constraining the presence of amphibole and mica in metasomatized mantle sources through halogen partitioning experiments
Autor: Stamatis Flemetakis, Arno Rohrbach, Felix S. Genske, Stephan Klemme, Andreas Stracke, Jasper Berndt
Publikováno v: Lithos. :105859
We present experimentally determined partition coefficients (Dmin/melt) for F and Cl between pargasite (amphibole), phlogopite (mica), clinopyroxene and basanitic melts. All experiments were performed at 1.4 GPa and temperatures between 1015 °C and

On the Color and Genesis of Prase (Green Quartz) and Amethyst from the Island of Serifos, Cyclades, Greece

Issue 11
Minerals, Vol 8, Iss 11, p 487 (2018)
The color of quartz and other minerals can be either caused by defects in the crystal structure or by finely dispersed inclusions of other minerals within the crystals. In order to investigate the mineral chemistry and genesis of the famous prase (gr
