In this paper we report crystal/groundmass partition coefficients of a large set of major and trace elements for the main phenocryst minerals occurring in the potassium -rich volcanic rocks from the Roman comagm atic province, Central-Southern Italy. Based on these data, the patterns of major and trace element variation during the low-pressure evolution of alkaline potassic magmas are briefly discussed.

Abstract
In this paper we report crystal/groundmass partition coefficients of a large set of major and trace elements for the main phenocryst minerals occurring in the potassium -rich volcanic rocks from the Roman comagm atic province, Central-Southern Italy. Based on these data, the patterns of major and trace element variation during the low-pressure evolution of alkaline potassic magmas are briefly discussed.File in questo prodotto:
