Structural, geochronological and P-T constraints on subduction-accretion processes in a Pan-African accretionary wedge – The Deep Level Southern Zone of the Damara Belt in Namibia
TL;DR: In this article, the authors combine structural data with P-T estimates and in-situ LA-ICP-MS U-Pb xenotime dating and Ar-Ar age determinations of mineral separates, to give insight into the dynamics of subduction and exhumation in the deeply eroded, tectonically interleaved Deep Level Southern Zone (DLSZ).
Journal ArticleDOI

TL;DR: In this article, a diamond-rich rock fragment called Hypatia was found in the area of south west Egypt in the south-western side of the Libyan Desert Glass strewn field.
Journal ArticleDOI
The Ediacarian-Cambrian uplift history of western Dronning Maud Land: New 40Ar-39Ar and Sr/Nd data from Sverdrupfjella and Kirwanveggan, the source of the Urfjell Group and tectonic evolution of Dronning Maud Land within the Kuunga Orogeny and Gondwana amalgamation
TL;DR: In this article, the authors show that the relative ages of hornblende and biotite from Kirwanveggan and Sverdrupfjella gneisses are consistent with rapid uplift in a single event.
Geochemistry of metabasalts from ophiolitic and adjacent distal continental margin units: Evidence from the Monte Rosa region (Swiss and Italian Alps)
TL;DR: In this paper, a whole rock analysis of amphibolites from the ophiolitic and adjacent continental tectonic units in the Monte Rosa region is presented, which indicates that they were derived from fractionated magmas with compositions ranging from Eto N-MORB.
