Rare earth element content in the Szentbékkála series of peridotite inclusions
The genetic relations of four nonfrequent xenolith inclusion groups (dunite, layered lherzolite, websteriteandspinel-pyroxenite) to the hypothetical mantle sourcespinel-lherzolite(themostfrequent inclusion) and to the host alkali basalts have been investigated. The concentrations of rare-earth eleme...

520 | 3 | |a The genetic relations of four nonfrequent xenolith inclusion groups (dunite, layered lherzolite, websteriteandspinel-pyroxenite) to the hypothetical mantle sourcespinel-lherzolite(themostfrequent inclusion) and to the host alkali basalts have been investigated. The concentrations of rare-earth elements (REE) in the basalts, in the peridotite inclusions and in the mineral separates of spinellherzolites and spinel-pyroxenites were determined by instrumental neutron activation analysis. The REE abundance patterns of peridotite inclusions show increasing REE concentrations in the order: dunite, spinel-lherzolite, layered lherzolite, websterite and spinel-pyroxenite. Except spinelpyroxenite this series of inclusions represents a gradation from depleted (the former two groups) to enriched (the later two groups) remnants of source mantle material. The enrichment of REE in spinel-pyroxenites and alkali basalts are in accord with their 17 percent and 3 percent partial melting from a chondritic mantle source. On the basis of our REE concentration measurements on alkali basalts containing peridotite inclusions (Szigliget, Szentbékkálla, Kapolcs) we suggest the introduction of a new group, the peridotite inclusion containing basalt group into GY .
