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 lithospheric mantle underneath the Gibeon Kimberlite field (Namibia): A mix of old and young components—Evidence from Lu–Hf and Sm–Nd isotope systematics
TL;DR: In this paper, major and trace elements and the Sm-Nd and Lu-Hf isotope systematics in minerals of 19 garnet peridotites from the Gibeon Townlands and Hanaus kimberlite pipes were determined.
Processes and Time Scales of Differentiation in Silicic Magma Chambers: Chemical and Isotopic Investigations
TL;DR: Snyder et al. as discussed by the authors investigated the processes responsible for the chemical and isotopic evolution of silicic magmas, and the time scales over which these processes are operative through the application of chemical data from plutonic (Alaska) and volcanic (Azores) rocks.

The age of continental roots
TL;DR: In this article, the authors used the Re-Os isotope system to date the mantle part of continental roots and their subsequent evolution in the cratons of the world's continents, and showed how the crust and mantle parts of continental lithospheric roots have remained coupled for billions of years.
Journal ArticleDOI
Decoupling of the Sm–Nd and Re–Os Isotopic Systems in Sulphide-Saturated Magmas in the Halls Creek Orogen, Western Australia
TL;DR: In this paper, the authors observed apparent decoupling of the Re-Os and Sm-Nd partitioning of Os into immiscible sulphide and showed that such processes would not affect the for chalcophile isotopic systems in turbulent sulphide-saturated lithophile Sm−Nd isotopic system.

TL;DR: Wehrlite xenoliths from the Early Cretaceous Tietonggou high-Mg diorites in western Shandong Province, in the eastern part of the North China Craton (NCC), were reported in this paper.

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.
