TLDR
Isotope analyses of Os, Sr, Nd, and Pb elements were caried out on twelve peridotite xenoliths from the Jagersfontein, Letseng-la-terae, Thaba Patsoa, Mothae, and Premier kimberlites of southern Africa, to investigate the timing and the nature of melt extraction from the continental lithosphere and its relation to the continent formation and stabilization.About:

The characterisation and origin of graphite in cratonic lithospheric mantle: a petrological carbon isotope and Raman spectroscopic study
D.G. Pearson,F. R. Boyd,Stephen E. Haggerty,Jill D. Pasteris,S. W. Field,P. H. Nixon,N. P. Pokhilenko +6 more
TL;DR: In this paper, the authors used X-ray diffraction and Raman spectra of peridotite-suite diamond inclusions to investigate the potential for graphite metastability in the mantle.
Hafnium Isotope and Trace Element Constraints on the Nature of Mantle Heterogeneity beneath the Central Southwest
TL;DR: MORB appears to be consistent with the hypothesis that this component represents fragments of subduction-modified lithospheric mantle beneath Proterozoic orogenic belts that foundered into the nascent Indian Ocean upper mantle during the Mesozoic breakup of Gondwana as discussed by the authors.
Journal ArticleDOI
Radiometric ages of basaltic achondrites and their relation to the early history of the solar system
TL;DR: In this article, the ages of three cumulate eucrites (Moama, Moore County, and Serra de Mage) and three non-cumulative eucrite (Nuevo Laredo, Bouvante, and Stannern) were determined.
Journal ArticleDOI
Stability and dynamics of the continental tectosphere
TL;DR: In this article, the authors investigate the long-term stability of the continental tectosphere by carrying out a number of numerical convection experiments within a two-dimensional Cartesian domain.
Journal ArticleDOI
Hotspot volcanism and highly siderophile elements
TL;DR: In this article, the highly siderophile element (HSE) geochemistry of hotspot volcanic rocks has been studied and used to understand the evolution of terrestrial hotspot volcanism.

On the regional variation of heat flow, geotherms, and lithospheric thickness☆
TL;DR: In this article, Pollack et al. constructed a global map of lithospheric thickness based on the regional variation of surface heat flow, geotherms, and lithosphere thickness, and identified the lid as synonymous with the lithosphere.

The composition and evolution of the continental crust: rare earth element evidence from sedimentary rocks
TL;DR: In this article, a revised andesite model is used to obtain total crustal composition, assuming that the upper crust, one-third of the total, is derived from intracrustal partial melting.
