Red beds are irrefutable evidence of important geological events; understanding their
formation mechanism and sedimentary environment provide insights about Earth's history …

Abstract The Proterozoic Era records two periods of abundant positive carbon isotope
excursions (CIEs), conventionally interpreted as resulting from increased organic carbon …

The Neoproterozoic Hüttenberg Formation in northeastern Namibia records a remarkable δ
13 C carb positive excursion with a sustained plateau of values up to+ 12‰(ie, the …

Increasing application of high precision uranium-lead (U-Pb) and rhenium-osmium (Re-Os)
geochronology to the ancient geological record has resulted in massive improvement in age …

While numerous studies have examined modern hypersaline ecosystems, their equivalents
in the geologic past, particularly in the Precambrian, are poorly understood. In this study …

Carbonate successions are principal geochemical archives of the extraordinary
environmental changes that occurred during the Neoproterozoic Era. In this study, we …

The terminal Ediacaran was a critical period in Earth history due to the coincidence of
climate change, seawater chemistry variability, biological innovation, and tectonic activity …

The timing of final assembly and initiation of subsequent rifting of Rodinia is disputed. New
rutile ages (913±9 Ma, 900±8 Ma and 873±3 Ma) and published zircon, monazite, titanite …

Emplacement and weathering of large igneous provinces (LIPs) can have dramatic effects
on global climate and biogeochemical systems. In the Phanerozoic, these events are often …

In the aftermath of the catastrophic end-Permian mass extinction, the Early Triassic records
recurrent perturbations in the carbon isotope signal, most notably during the Smithian and …
