Metacraton: nature, genesis and behavior
In this paper, we show with examples that cratons involved in intercontinental collisions in a
lower plate position are often affected by orogenic events, leading to the transformation of …

Sr–Nd isotopes and geochemistry of granite-gneiss complexes from the Meatiq and Hafafit domes, Eastern Desert, Egypt: no evidence for pre-Neoproterozoic crust
Neoproterozoic gneisses at Meatiq and Hafafit in the Eastern Desert of Egypt give Rb–Sr

A reappraisal of the global tectono-magmatic lull at∼ 2.3 Ga
Abstract There is a 87–86% drop in frequency in both detrital and igneous zircon U/Pb ages
during the Tectono-Magmatic Lull (TML, 2365–2235 Ma) and a significant decrease in …
