Stratigraphy articles from across Nature Portfolio

An article in Geology shows how enhanced oxidative weathering could have stimulated the evolution of complex life in the Ediacaran, by increasing nutrient availability and ocean–atmosphere oxygen levels.

An article in Palaeogeography, Palaeoclimatology, Palaeoecology describes how high-productivity intervals during Oceanic Anoxic Event 2 were related to the influence of freshwater runoff.

An article in Geochimica et Cosmochimica Acta reports a Nd-isotope record of terrestrial dust from northern Tibetan Plateau sediments since 52 Ma, revealing insight into regional uplift and climate changes from inland Asia.

Confidence that banded iron formations record oxic conditions during deposition is established, as a model demonstrates that they are formed of primary iron oxides rather than secondarily altered silicate minerals.
