Eight elinopyroxenes from wehrlites and clinopyroxenites and three clinopyroxenes of crystal lapilli in tuff of Dreiser Weiher in Eifel, Germany, have been separated and chemically analysed. One hornblende and two phlogopites from a wehrlite and clinopyroxenites have also been analysed. The rocks enclosing these inclusions are alkali basalts of basanite composition. The analysed clinopyroxenes contain considerable amounts of AI~O 3 (3.87--10.84 wt % ). The calculated Tschermak's component ranges from 5.9 to 18.4 reel per cent. All of the analysed clinopyroxenes are clearly different from chromian diopsides in lherzolite inclusions in basaltic rocks in I)reiser Weiher and other localities; the former has higher contents of total FeO, CaO and TiO 2 and lower contents of MgO and Cr203 than the latter. Two elinopyroxenes separated from apatite-bearing clinopyroxenites show high contents of Fe20 a with about 2 per cent of Na20, indicating the presence of considerable amounts of acmite component in addition to Tschermak's component. The relative proportions of A1 in the tetrahedral site and that in the octahedral site in the analysed elinopyroxenes are clearly different from those of the common igneous clinopyroxenes and eclogites, and similar to those of the clinopyroxenes from other inclusions in basaltic rocks and granulites. It is suggested that all the analysed clinopyroxenes and their host inclusions have crystallized from alkali basalt magmas in relatively deep levels of the continental crust.
