Studies of mantle xenoliths have confirmed that Archean subcontinental lithospheric mantle
(SCLM) is highly depleted in basaltic components (such as Al, Ca and Na) due to high …

La provincia basáltica Payenia se desarrolló al pie de los Andes entre 33º40'S y 38ºS. Es
una típica asociación de retroarco con dos picos de actividad, el más antiguo es …

Mantle xenoliths usually represent fragments derived from the depleted and degassed
lithospheric mantle with 3He/4He isotope ratios (6±1 RA) lower than those of mid-ocean …

We present a structural update to the thermodynamic model for calculating peridotite phase
relations and melt compositions at 0· 01 to 60 kbar and from 600° C to the peridotite liquidus …

A REE-in-garnet–clinopyroxene thermobarometer for eclogites, granulites, and garnet
peridotites has been developed on the basis of the temperature, pressure and mineral …

The thermochemical evolution of oceanic lithosphere and its interaction with the underlying
asthenosphere exerts a fundamental control on the dynamics of the Earth system. Since the …

The alkaline volcanic rocks of the 1.8–0.9 Ma Auca Mahuida and post-mid-Pliocene Rio
Colorado backarc volcanic fields east of the Andean Southern Volcanic Zone at~ 37°–38° S …

The Earth's upper mantle extends from below the crust to a depth of about 410 km. Here, we
review the mineralogical and chemical composition of the upper mantle, especially with …

Complex multiphase reaction rims that form during garnet breakdown are known as
kelyphite coronae and are common amongst exhumed mantle xenoliths. It has long been …

Chemistry of detrital garnets, chrome spinels and tourmalines of 30 selected samples in
combination with the general heavy mineral distribution from 523 sandstone samples of the …
