Syn-volcanic melt-rock reactions recorded in peridotitic xenoliths from Scania, S Sweden

Mineralogia
Peridotite xenoliths from Scania (S Sweden), brought to the surface by Mesozoic basanitic magmas, provide insights into the lithospheric mantle underlying the East European Craton.

The problem of identifying lower crustal garnet-clinopyroxene granulites and mantle eclogites: a case study of xenoliths from the V.Grib pipe

Записки Горного института
The article presents a comprehensive analysis of the mineralogical and geochemical features of xenoliths from the V.Grib kimberlite pipe, represented by lower crustal garnet-clinopyroxene granulites and mantle eclogites. A comparative characterization of

Geochemistry of forty‐one eclogitic and pyroxenitic mantle xenoliths from the Central Slave Craton, Canada (Ekati Diamond Mine)

Geoscience Data Journal
This article describes a novel dataset on non‐diamondiferous eclogite and garnet pyroxenite xenoliths from four kimberlite pipes of the Ekati Diamond Mine (Central Slave Craton, Canada). Xenoliths brought to the surface by kimberlite eruptions are direct

A seismological study of the mantle beneath Iceland [PDF]

, 2000
Iceland has long been thought to be underlain by a thermal upwelling, or plume, rising from deep within the mantle. This study tests this hypothesis, by a) seeking evidence for a plume in the lower mantle in azimuth anomalies at the NORSAR array and b ...

Compositional trends of Icelandic basalts: Implications for short–length scale lithological heterogeneity in mantle plumes [PDF]

Lithological variations in the mantle source regions under mid-ocean ridges and ocean islands have been proposed to play a key role in controlling melt generation and basalt composition.
