Journal ArticleDOI
Thermal state and redox conditions of the Kaapvaal mantle: A study of xenoliths from the Finsch mine, South Africa
TL;DR: A total of 28 peridotite xenoliths from the Finsch mine, South Africa, have been studied to assess the geotherm and redox conditions at depth in the subcontinental lithospheric mantle.
Journal ArticleDOI
The lead and copper isotopic composition of copper ores from the Sierra Morena (Spain)
TL;DR: In this paper, lead and copper isotope analyses of 51 copper ore samples from the Sierra Morena, South of Spain, were performed to distinguish between either sulphide ore or oxide ore deposit derived artefacts.
Journal ArticleDOI

TL;DR: In this article, the power of high pressure-high temperature (HP-HT) route for synthesis of binary nitrides has been demonstrated by the discovery of a novel hard tantalum nitride, exhibiting U2S3 structure.
Journal ArticleDOI
Melting of K-rich carbonated peridotite at 6-10GPa and the stability of K-phases in the upper mantle
TL;DR: In this article, the melting of two peridotite compositions (depleted hazburgitic and fertile lherzolitic) with Mg and K carbonates (1.4 and 6.8% K 2 O in the bulk compositions) was carried out at 6-10 GPa using a multianvil apparatus.
Journal ArticleDOI
Peridotitic diamonds from the Slave and the Kaapvaal cratons—similarities and differences based on a preliminary data set
TL;DR: A comparison of the diamond productions from Panda and Snap Lake with those from southern Africa shows significant differences: diamonds from the Slave typically are unresorbed octahedrals or macles, often with opaque coats, and yellow colours are very rare.
