Clinopyroxenes from ultramafic inclusions (spinel lherzolites and wehrlites) included in European Tertiary basalts (Massif Central, France; Dreiser Weiher and Vogelsberg, Germany and Kapfenstein, Austria) were analyzed for major elements by microprobe and trace elements by neutron activation. The REE pattern of the clinopyroxenes reflect the bulk composition of the inclusion and from the combination of major and trace elements a similar complex history arises for the inclusions as for those described by Frey and Green, 1974 and Frey and Prinz, 1978. It is shown that Yb and Sc increase with the jadeite and jadeite+Tschermaks component, resp., in the clinopyroxene and it is concluded that the uptake into clinopyroxene of such trace elements is a function of major element composition and probably pressure and temperature.
