High-MgO lamproite and lamproite-like (ie lamprophyric) ultrapotassic rocks are recurrent in
the Mediterranean and surrounding regions. They are associated in space and time with …

Deep melt intrusion and melt-peridotite interaction may introduce small-scale heterogeneity
in the MORB mantle. These processes generate pyroxenite-bearing veined mantle that …

Subduction-transform edge propagator (STEP) faults are the locus of continual lithospheric
tearing at slab edges, resulting in sharp changes in the lithospheric and crustal thickness …

Spinel peridotite xenoliths (one plagioclase-bearing) hosted in alkaline basalts from Tallante
(southeast Spain) record the mineralogical and geochemical fingerprint of the …

Peridotite xenoliths collected from alkali basalts in the Argentinian Patagonia reveal the
existence of an ancient depleted Paleoproterozoic mantle that records a subsequent …

Ultramafic xenoliths are rarely found at convergent plate margins. A notable exception is in
the Betic Cordillera of southern Spain, where the eruption of xenolith-bearing alkaline …

Mantle xenoliths in the 20 Ma Wilcza Góra basanite (Lower Silesia, NE Bohemian Massif)
are mostly harzburgites, some with amphibole which is exceptional in the region. Forsterite …

ABSTRACT South-Eastern Spain is a key locality of the Western Mediterranean to unravel
the origin of post-collisional magmatism and its relationships with the multi-stage evolution …

A simple method was developed for the determination of REEs, Zr, Hf, Th and U in ultramafic
rocks by inductively coupled plasma‐mass spectrometry with a combination of RE and …

The microstructural relationship between olivine and clinopyroxene is significant in
recovering the mantle evolution under clinopyroxene-saturated melting conditions. This …
