Cryptic metasomatism revealed by Li isotopes of mantle xenoliths beneath the Thrace Basin, NW Turkey

To identify metasomatic overprints in the mantle xenoliths from the Tethys orogenic belt in NW Turkey, we report here in situ Li concentrations and isotopic compositions of olivine, clinopyroxene and orthopyroxene along with major element compositions of minerals, and whole-rock trace element compositions of the mantle xenoliths composed of refractory harzburgites with subordinate lherzolites and one olivine-websterite. Their non-depleted...
