Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Plate tectonics describes the horizontal motion of rigid lithospheric plates away from
midoceanic ridges and parallel to transforms, towards deep-sea trenches, where the …

During the early Archaean, the Earth was too hot to sustain rigid lithospheric plates subject
to Wilson Cycle-style plate tectonics. Yet by that time, up to 50% of the present-day …

Zircon trace element geochemistry has become an increasingly popular tool to track crustal
evolution through time. This has been especially important in early-Earth settings where …

Abstract The Middle Marker–horizon H1 of the Hooggenoeg Formation–is the oldest
sedimentary horizon in the Barberton greenstone belt and one of the oldest sedimentary …

Phosphorus (P) is the key nutrient thought to limit primary productivity on geological
timescales. Phosphate levels in Archean marine sediments are low, but quantification of the …

The initiation of mobile-lid plate tectonics on Earth represented a critical transition towards a
more familiar world in terms of surface temperature stabilization, biogeochemical cycling …

Previous work has shown that Devonian magmatism in the southern Andes occurred in two
contemporaneous belts: one emplaced in the continental crust of the North Patagonian …

Abstract The Moodies Group is the uppermost and youngest unit of the Barberton
Supergroup, the volcanic-sedimentary sequence forming the Barberton Greenstone Belt …

Abstract The Makhonjwa Mountains, traditionally referred to as the Barberton Greenstone
Belt, retain an iconic Paleoarchean archive against which numerical models of early earth …
