Mg-metasomatism and formation conditions of Mg-chlorite-muscovite-quartzphyllites (leucophyllites) of the eastern Alps (W. Hungary) and their relations to Alpine whiteschists
Article Abstract:
The field relationships, chemical and stable oxygen and hydrogen isotope compositions of leucophyllites of the Sopron Hills in West Hungary are studied. The formation of leucophyllites occurred in shear zones and are associated with alkali and iron depletion, and the enrichment of magnesium and water. It is argued that the metasomatic processes that formed that Mg-rich rocks could be similar to the processes that led to the formation of high pressure whiteschists in the Central and Western Alps.

Experimental modal metasomatism of a spinel lherzolite and the production of amphibole-bearing peridotite
Article Abstract:
Modal metasomatism of spinel lherzolite by siliceous melts results in the formation of pargasitic amphiboles. The composition of these metasomatic mineral assemblage is highly similar to that of amphiboles found in amphibole-containing peridotites found in supra-subduction environments. Differences observed in the composition of the amphiboles can be attributed to continuous modification of infiltrating melt composition during the infiltration process of the experiment.

Experimental cpx/melt partitioning of 24 trace elements
Article Abstract:
An analysis describing cpx/melt partitions for 24 trace elements is presented. The partition coefficients have been tested by ion probe at natural levels. The analysis aimed to intercompare Ds for high-field-strength elements and rare earth elements (REE). It is shown that Hf and Ti exhibited no anomaly, while Zr was observed for a major negative anomaly. In addition, incompatible elements such as Ba, K and Nb were grouped among published values.
