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 …

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 …

Unlike in the ocean basins where the shallow mantle eventually contributes to the
destruction of the overlying crust, the shallow mantle beneath continents serves as a stiff …

Most diamonds form in a relatively narrow depth interval of Earth's subcontinental mantle
between 150 and 250 km. From carbon isotope analyses of diamond obtained in the 1970s …

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

Micro-inclusions in cloudy diamonds from Koffiefontein consist of three main types: silicates,
carbonates and brine inclusions. The silicates belong to either the eclogitic or the peridotitic …

Since first being discovered in India over 2000 years ago, the most striking and universally
recognized shape of an uncut diamond is the octahedron. This shape was revered from …

The analysis of micro-inclusions in fibrous diamonds from the Diavik mine, Canada revealed
the presence of high density fluids (HDFs) that span a continuous compositional range …

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 …

Syngenetic diamond inclusions from the Mwadui kimberlite reveal that an unusually fertile
section of lithospheric mantle beneath the Central African Craton was sampled. This is …
