Hydrous Asthenosphere Underneath the Northern Pannonian Basin
ABSTRACT This study reveals the structural hydroxyl content in clinopyroxenes of three cumulate xenoliths from the Nógrád‐Gömör/Novohrad‐Gemer Volcanic Field (northern Pannonian Basin), with values ranging from 275 to 384 ppm. Based on these data, the water content of the equilibrium parental alkali basaltic melt was estimated to be between 1.5 and 2.1

Enrichment of incompatible elements at grain-boundaries of olivine in an olivine-nephelinite.
Variations in the concentrations of trace elements at and near the subgrain-boundaries within olivine phenocrysts in an olivine-nephelinite were inspected with an electron microprobe. The olivine phenocrysts show homogeneous core (Fo85) surrounded by the Fe-richer rim.
