Abstract The early Toarcian Oceanic Anoxic Event (Jenkyns Event) was associated with
major world-wide climatic changes with profound effects on the global carbon cycle. This …

Abstract The Early Jurassic Toarcian oceanic anoxic event (T-OAE) is characterized by an
extinction event, a major sea-level rise, enhanced marine primary productivity, elevated …

Apparent synchrony between eruption/emplacement of large igneous province (LIP)
magmas and mass extinction has led to the implication of magmatism as a primary trigger of …

Abstract The Early Jurassic was marked by multiple periods of major global climatic and
palaeoceanographic change, biotic turnover and perturbed global geochemical cycles …

The loss of carbonate production during the Toarcian Oceanic Anoxic Event (T-OAE, ca. 183
Ma) is hypothesized to have been at least partly triggered by ocean acidification linked to …

Abstract The Triassic–Jurassic transition, which is here broadly defined as extending from
the Late Triassic through the Early Jurassic (~ 237 Ma to 174 Ma), was an important interval …

Potential temporal and causal connections among various geologic events have long been
discussed in the geological literature. More recently, signs of common periodicities in these …

This paper reports new paleomagnetic and geochronologic data from a~ 1500 m thick
composite section belonging to the Drakensberg group, the thickest remnant of the Karoo …

Abstract The early Toarcian Oceanic Anoxic Event (T-OAE, or Jenkyns Event,~ 183 million
years ago) was a major hyperthermal and global carbon-cycle perturbation, likely …

Astronomical forcing has been shown to be a fundamental driver of climate change through
geological time. Pelagic, bedded cherts deposited in Mesozoic ocean basins with chert …
