Magnesium (Mg) has an atomic number of 12 and belongs to the alkaline earth element
(Group II) of the Periodic Table. The pure Mg is a silvery white metal and has a melting point …

Continents, especially their Archean cores, are underlain by thick thermal boundary layers
that have been largely isolated from the convecting mantle over billion-year timescales, far …

Mantle temperatures during the Archaean eon were higher than today. As a consequence,
the primary crust formed at the time is thought to have been extensive, thick and magnesium …

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

Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich
eclogites) and ultramafic rocks from the depth interval of 100–680 m of the Chinese …

The origin of cratonic diamonds is reviewed on the basis of nearly 5000 analyses of silicate,
oxide and sulphide inclusions in diamonds. Compositional fields are defined for common …

Many oceanic-island basalts (OIBs) with isotopic signatures of recycled crustal components
are silica poor and strongly nepheline (ne) normative and therefore unlike the silicic liquids …

Many ocean island basalts (OIB) that have isotopic ratios indicative of recycled crustal
components in their source are silica-undersaturated and unlike silicic liquids produced from …

Presenting a coherent synthesis of lithosphere studies, this book covers a range of
geophysical methods (seismic reflection, refraction, and receiver function methods; elastic …

Eclogites from the Earth's mantle found in kimberlites provide important information on
craton formation and ancient geodynamic processes because such eclogites are mostly …
