The alkaline volcanism of the Cameroon Volcanic Line in its northern domain has raised many fresh enclaves of peridotites. The samples selected come from five (05) different localities (Liri, in the plateau of Kapsiki...
Numerous mantle xenoliths 6–12 cm in size and sub-angular to rounded in shape occur within Mio-Pliocene basanite lavas of the monogenic volcano of HosséréSédé in the Adamawa plateau.Xenoliths of spinel lherzolite...

Mantle peridotite xenoliths in Jiaohe City,located near the northern part of the Tan-Lu fault,are key evidence for constraining the nature and evolution of the subcontinental lithospheric mantle(SCLM)of the NE China.G...

The lower crust beneath the North China Craton(NCC)was transformed during the craton destruction in the Mesozoic,however,the transformation processes are yet to be fully understood.Compositional and geochronological v...
Peridotite xenoliths,raised to the surface by alkaline basalts or kimberlites,provide us direct information on the processes and composition of the upper mantle.They are the major source of information on the state of...
Xenoliths enclosed in Lavas of the Nyos volcano (Cameroon Volcanic Line, continental sector) range from fertile lherzolites to harzburgites. One spinel-free wehrlite has been also sampled. The occurrence of phlogopite...
Volcanic deposits from the lake Nyos contain ultramafic xenoliths: lherzolites, harzburgites and wehrlites, sometimes containing amphiboles and phlogopites. The lithospheric mantle beneath Nyos, as inferred from chemi...
Abu Rusheid area lie in the south of the Eastern Desert of Egypt and comprises(1)ophiolitic mélange,consisting of ultramafic rocks and layered metagabbros in metasedimentary matrix(2)cataclastic group,consisting of p...

The Cenozoic basalts exposed in Bo Phloi Gem Field,Kanchanaburi Province,western Thailand are a host to different gem materials(e.g.,sapphire,black spinel,black pyroxene and zircon)as well as other xenocrysts and xeno...
