Clinopyroxene with diverse origins in alkaline basalts from the western Pannonian Basin: Implications from trace element characteristics

We show that in situ trace element analysis is necessary in order to unravel the origins and relationships of the diverse clinopyroxene populations. Such studies significantly contribute to our understanding of the ascent histories of alkaline basaltic magmas and provide information about the characteristics of the rocks that constitute the lithosphere. Additionally, the abundance of foreign crystals incorporated in the ascending basaltic magmas, and their potential for contamination of the host magma, must be taken into account when whole-rock geochemical data are interpreted.
