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 …

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 …

Almost immediately after the discovery of kimberlites, the atten tion of investigators was
attracted to their unusual mineralogy. It has been established that, besides the fragments …

Mantle-derived garnets recovered in diamond exploration programs show compositional
variations in Cr, Ca, Mg, Fe and Ti that reflect the chemical, physical and lithological …

На основе детального изучения состава и парагенезисов гранатсодержащих основных
и ультраосновных пород, известных в виде ксенолитов в кимберлитовых трубках …

The lithosphere–asthenosphere boundary (LAB) is a first-order structural discontinuity that
accommodates differential motion between tectonic plates and the underlying mantle …

This chapter is devoted to the carbon and nitrogen stable isotope compositions of terrestrial
diamonds with a strong focus on monocrystalline diamonds formed in Earth's mantle. The …

Sub-calcic garnets encapsulated by diamonds from relatively young (90 Myr) kimberlites in
southern Africa, yield ancient Sm–Nd and Rb–Sr model ages (3,200–3,300 Myr). The …

A suite of peridotite xenoliths from kimberlites intruding the Siberian craton indicate the
presence of lithospheric mantle over 150 km thick at 350 Ma. We report Sr-Nd isotope data …
