A review of carbon isotope excursions, redox changes and marine red beds of the Early Triassic with insights from the Qinling Sea, northwest China
H Li, PB Wignall, H Jiang, M Zhang, X Wu, X Lai - Earth-Science Reviews, 2023 - Elsevier
Abstract The Early Triassic was an interval characterized by frequent, large global carbon
isotope excursions (CIEs), multiple and widespread anoxic phases, and generally high but …

Recovery from persistent nutrient-N limitation following the Permian–Triassic mass extinction
Global warming, widespread oceanic anoxia and stagnation, and large perturbations of the
global carbon cycle characterized the end-Permian to Middle Triassic interval. Nitrogen …

Conodont calcium isotopic evidence for multiple shelf acidification events during the Early Triassic
The marine calcium (Ca) cycle is controlled by rates of continental weathering, seawater pH,
and carbonate deposition on the seafloor and is linked to atmospheric CO 2, climate …

High-resolution Early Triassic ammonoid biostratigraphy of South Tibet, China and implications for global correlations
Ammonoids are key fossil indexes for Triassic biochronology, as all Triassic stages and
substages were initially defined on ammonoid faunas. In recent decades, the temporal …

Transient Permian-Triassic euxinia in the southern Panthalassa deep ocean
Both the duration and severity of deep-water anoxic conditions across the Permian-Triassic
mass extinction (PTME) are controversial. Panthalassa Ocean circulation models yield …

[HTML][HTML] Comparative geochemistry of Early Carboniferous marine red beds (MRBs) and their significance for deep time paleoceanographic reconstructions
CJ Card, M Montenari - Sedimentary Geology, 2023 - Elsevier
Marine red beds (MRBs), also known as oceanic red beds (ORBs), are reddish colored
sediments deposited within the marine realm that have been stained during deposition …
