Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

TTGs (tonalite–trondhjemite–granodiorite) are one of the archetypical lithologies of
Archaean cratons. Since their original description in the 1970s, they have been the subject …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

Adakite was originally proposed as a genetic term to define intermediate to high-silica, high
Sr/Y and La/Yb volcanic and plutonic rocks derived from melting of the basaltic portion of …

Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

Plate tectonic processes introduce basaltic crust (as eclogite) into the peridotitic mantle. The
proportions of these two sources in mantle melts are poorly understood. Silica-rich melts …

More than 50 per cent of the Earth's upper mantle consists of olivine and it is generally
thought that mantle-derived melts are generated in equilibrium with this mineral. Here …

Abstract Early History of Mantle GeochemistryUntil the arrival of the theories of plate
tectonics and seafloor spreading in the 1960s, the Earth's mantle was generally believed to …

There is no consensus on the processes responsible for near-coeval formation of Archaean
continental crust (dominantly tonalite–trondhjemite–granodiorite: TTG), greenstone belts …

A review of experiments on natural peridotites allows improved constraints on the location of
the mantle solidus. Available constraints on the location of the nominally dry peridotite …
