Abstract: | The isotopic composition of strontium, and rubidium and strontium concentrations in eight ultramafic inclusions and two host
basalts from Dreiser Weiher, Eifel, Germany are presented. Comparison of the 87Sr/86Sr ratios of the inclusions with the basaltic hosts indicates that the lherzolite inclusions are exotic in nature but the
wehrlite-clino-pyroxenites are probably cognate with the host rocks. An apparent age of 550 m.y. (±a large uncertainty) shown
by the lherzolites is believed to reflect a mantle event. |
