Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
Jacob and Mikhail 2022, this volume) nor a common crustal mineral (the exceptions being …

The oxygen isotope ratios of Phanerozoic zircons from kimberlite pipes in the Kaapvaal
Craton of southern Africa and the Siberian Platform vary from 4.7 to 5.9‰ VSMOW. High …

Occurrence and ClassificationFragments of the Earth's mantle are frequently transported to
the surface via volcanic rocks that are dominantly alkaline in nature. These fragments range …

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 …

This article summarises data on the formation of commercial-sized diamonds
(macrodiamonds) from kimberlitic rocks. A brief review of previous work and ideas is …

Diamond crystallization ages are essential information for science and industry, leading to
an understanding of how, why, and where diamonds form in Earth and how best to find …

Cratonic lithospheric mantle plays an integral role in defining the physical behaviour of
ancient continents and their mineral potential. Bulk compositional data show that modern …

Diamonds form in the upper mantle during episodic events and have been transported to the
Earth's surface from at least the Archean to the Phanerozoic. Small diamonds occur as …

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 …
