Astronomical calibration of the Toarcian Stage: Implications for sequence stratigraphy and duration of the early Toarcian OAE [PDF]

Earth and Planetary Science Letters, 2014
The Toarcian Oceanic Anoxic Event (T-OAE) of the early Jurassic period involves one of the largest perturbations of the carbon cycle in the past 250 Ma, recorded by a pronounced negative carbon-isotope excursion (CIE). Numerous studies have focused on potential causes of the T-OAE and CIE, but are hampered by an uncertain timescale.

Calibrating the magnitude of the Toarcian carbon cycle perturbation [PDF]

Paleoceanography, 2015
AbstractSedimentary rocks recording the Toarcian oceanic anoxic event (T‐OAE) are marked by a negative carbon isotope excursion (CIE) reaching up to −7‰ and ranking among the largest known in the Phanerozoic. These records suggest a dramatic perturbation of the carbon cycle that has been linked to the transfer of juvenile carbon from the endogenic to ...

Toarcian land vegetation loss

Nature Geoscience, 2019
The Toarcian oceanic anoxic event disrupted terrestrial ecosystems as well as the marine realm, according to analyses of microfossils derived from land plants. Changes in diversity and composition were initially more rapid in terrestrial ecosystems.

Late Pliensbachian–Early Toarcian palaeoenvironmental dynamics and the Pliensbachian–Toarcian Event in the Middle Atlas Basin (Morocco)

International Journal of Coal Geology, 2020
Abstract Geochemical and palynofacies analysis of 38 samples from the Middle Atlas Basin (Ait Moussa and Issouka sections, Morocco) allowed to investigate sea-level changes, climate, and tectonics and impact on depositional environments in the westernmost Tethyan Gondwana-margin during the Late Pliensbachian–Early Toarcian and the Pliensbachian ...
