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 …

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 …

Geochemical data have been interpreted as requiring that a significant fraction of the melting
in MORB source regions takes place in the garnet peridotite field, an inference that places …

This remarkable volume presents the first revision to the classification system of diamond-
bearing rocks in over eighty years. Presenting the latest mineralogical data, this book offers …

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

To better understand the genetic relationship between granitoid rocks of the Archean
cratons and the underlying 'keel'of subcratonic lithospheric mantle (SCLM), we have …

We have investigated eight diamond-bearing bimineralic eclogite xenoliths from the
Udachnaya Mine, Yakutia, Siberia, in terms of major elements, 87 Sr 86 Sr−, 143 Nd 144 Nd …

We have experimentally investigated a K-bearing altered mid-ocean ridge basalt (MORB)
composition to which 10% CaCO3 was added (GA1+ 10% cc), at temperatures of 1050 …

Following the discovery of diamonds in river deposits in central South Africa in the mid
nineteenth century, it was at Kimberley where the volcanic origin of diamonds was first …

Geophysical discontinuities in Earth's upper mantle and experimental data predict the
structural transformation of pyroxene to garnet and the solid-state dissolution of pyroxene …
