Kelp forests are in decline across much of their range due to place‐specific combinations of
local and global stressors. Declines in kelp abundance can lead to cascading losses of …

Joint application of the Mo isotope paleoredox proxy and Re–Os deposition-age
geochronometer to euxinic black shales has potential for tracing the evolution of ocean …

The Tuolugou cobalt–(gold) deposit, in the northeastern margin of the Qinghai–Tibetan
plateau and central part of the eastern Kunlun orogenic belt, is the most recently discovered …

Emerging geochemical evidence suggests that the atmosphere-ocean system underwent a
significant decrease in O 2 content following the Great Oxidation Event (GOE), leading to a …

Global correlations of Precambrian stratigraphic successions can be hampered by the
coarse resolution of biostratigraphic and chemostratigraphic records, and by the scarcity of …

Here we present initial 187Os/188Os (Osi) values integrated with δ13Corg for the first
Paleozoic section—the Ordovician/Silurian boundary GSSP at Dob's Linn, Scotland. Our …

The end of Permian time (252–251Ma) hosts the largest mass extinction in Earth history, yet
events heralding this global catastrophe remain intensely disputed. We present a …

Abstract The Re–Os and major element geochemistry of an expanded gray shale sequence
from the Central Basin in Spitsbergen, Svalbard Archipelago (Norway) over the Paleocene …

Pyroxenitic layers are a minor constituent of ultramafic mantle massifs, but are considered
important for basalt generation and mantle refertilization. Mafic spinel websterite and garnet …

We present a compilation of 192 Os concentrations (representing non-radiogenic Os) and
initial 187 Os/188 Os isotope ratios from organic-rich mudrocks (ORM) to explore the …
