East Meets West: The Trace of the Mesoproterozoic Kibaran Event in the Mantle Lithosphere Beneath Eastern Tanzania

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We present elemental geochemistry and multiple isotopic systematics (Re‐Os, Lu‐Hf, Sm‐Nd and Sr) for mantle peridotite xenoliths from Lashaine in northern Tanzania. We use the data to examine how the major Proterozoic tectono‐thermal events that affected the crust of the western Tanzanian craton are imprinted on the lithospheric mantle in the ...

From Compression to Extension in the Eastern Pyrenees: New Insights From Low‐Temperature Thermochronology

Tectonics, Volume 45, Issue 1, January 2026.
Abstract The tectonic evolution of the Eastern Pyrenees from the orogenic mountain building to the post‐orogenic dismantling is still debated. Since the Oligocene, the Gulf of Lion rifting in the Western Mediterranean superimposed crustal extension in this eastern part of the Pyrenean belt, while compressional tectonics persisted in the Central ...

The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.
