Knowledge of temperature and pressure, however qualitative, has been central to our views
of geology since at least the early 19th century. In 1822, for example, Charles Daubeny …

One of the key scientific questions about diamonds is “how are they formed?” To answer this
question, we need to know the diamond-forming reactions and the physicochemical …

Experimental clinopyroxenes synthesized at 850–1500° C and 0–60 kbar in the CMS and
CMAS-Cr systems and in more complex lherzolitic systems have been used to calibrate a Cr …

Major-and trace-element analyses of garnets from heavy-mineral concentrates have been
used to derive the compositional and thermal structure of the subcontinental lithospheric …

The lithosphere–asthenosphere boundary (LAB) represents the base of the Earth's
lithosphere, the rigid and relatively cool outer shell characterised by a conductive thermal …

The abundances of the mildly incompatible elements Al, Cr, V, Sc and Yb in more than 1700
mantle peridotite bulk rock analyses are interpreted in the light of a fractional melting model …

A suite of metasomatised xenoliths from the Letlhakane kimberlite (Botswana) forms a
metasomatic sequence from garnet peridotite to garnet phlogopite peridotite to phlogopite …

This study provides an experimental calibration of the empirical Al-in-olivine thermometer for
mantle peridotites proposed by De Hoog et al.(2010). We report Al concentrations measured …

The major-element composition of a grain of peridotitic Cr-pyrope garnet, coupled with a
temperature estimate (TNi) derived from its Ni content, can be used to calculate the forsterite …

The thermobarometric analysis of inclusions in lithospheric diamonds has shown that these
diamonds may originate from a wide range of depths, with a global mode at~ 175±15 km …
