Evolution of the South Pacific's Iron Cycle Over the Cenozoic

Paleoceanography and Paleoclimatology, Volume 40, Issue 7, July 2025.
Abstract Iron (Fe) availability impacts marine primary productivity, potentially influencing the efficiency of the biological carbon pump. Stable Fe isotope analysis has emerged as a tool to understand how Fe is sourced and cycled in the water column; however its application to sediment records is complicated by overlapping isotope signatures of ...

The Early Evolution of a Young Normal Fault in the Aysén Fjord, Chile

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Seismic reflection data have been used to investigate the evolution of faults in oil and gas basins for decades and typically image deeply buried faults at low resolution, with biostratigraphic age control to date horizons at scales of 10 Myr.

Rupture and Relamination of Continental Lithosphere in a Subduction System (Variscan Orogeny, SW Iberia)

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.

The Inter‐Cratonic Neoproterozoic Katangan Basin of Central Africa: Rift Basin Formation, Orogenic Inversion and Potential Fluid Pathways

Tectonics, Volume 44, Issue 7, July 2025.
Abstract The tectono‐stratigraphic development of continental basins is critical to an understanding of continental tectonics and the formation of metal deposits. The Neoproterozoic, inter‐cratonic Katangan copper basin of Central Africa records a tectono‐stratigraphic evolution and the generation of potential metal transporting fluid pathways ...

Lithospheric Unzipping Explaining Hot Orogenesis During Continental Subduction

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Phanerozoic accretionary orogens typically contain upper crustal nappes derived from subducted lithosphere—oceanic or continental—that display (ultra‐)high‐pressure, low‐temperature ((U)HP‐LT) metamorphism. Surprisingly, such orogens often also contain coeval continent‐derived nappes that underwent “Barrovian” (MP‐HT) syn‐burial metamorphism ...
