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 Mantle and Basalt-Crust Interaction Below the Mount Taylor Volcanic Field, New Mexico [PDF]

, 2010
The Mount Taylor Volcanic Field (MTVF) lies on the Jemez Lineament on the southeastern margin of the Colorado Plateau. The field is centered on the Mt. Taylor composite volcano and includes Mesa Chivato to the NE and Grants Ridge to the WSW.

How Cratonic Roots Survive With Weak Mid‐Lithosphere Discontinuities

Geophysical Research Letters
The stability of cratons has long been attributed to their neutral buoyancy and strong roots. However, recent seismic studies have revealed widespread mid‐lithospheric discontinuities (MLDs) within cratonic roots.

Geodynamic implications of xenolith geotherms

Geochemistry, Geophysics, Geosystems, 2003
Studies of xenolith suites yield depth‐temperature arrays for the lithosphere at the time of eruption. These studies constrain the conductive heat flow through the lithosphere and limit the temperature range across the rheological boundary layer to <300 K. Numerical models of convection illustrate features that may be found within suites of samples.

Peridotite pyroxenite and granulite xenoliths from Cenozoic Shavaryn Tsaram volcanic center (Mongolia): New data

Geosystems and Geoenvironment
Mantle lherzolites (spinel- and garnet-bearing), megacrysts and pyroxenites from Moho and lower crust xenoliths of the Cenozoic basalts of Shavaryn-Tsaram volcanic center were newly studied by the EPMA, SEM and LA-ICP methods to define more precisely ...
