Euxinic ocean conditions accompanied significant events in Earth history, including several
Phanerozoic biotic crises. By critically examining modern and ancient euxinic environments …

This paper reviews global records of anoxic events of the Middle Devonian–earliest
Mississippian, as well as the possible triggers and controls of these events. These “anoxic …

The temporal link between large igneous province (LIP) eruptions and at least half of the
major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of …

The early evolutionary and much of the extinction history of marine animals is thought to be
driven by changes in dissolved oxygen concentrations ([O2]) in the ocean,–. In turn,[O2] is …

The temporal link between mass extinctions and large igneous provinces is well known.
Here, we examine this link by focusing on the potential climatic effects of large igneous …

Abstract The Mississippian Barnett Formation of the Fort Worth Basin is a classic shale-gas
system in which the rock is the source, reservoir, and seal. Barnett strata were deposited in a …

Size analysis of pyrite framboids has been undertaken on epicontinental Permian–Triassic
boundary sections throughout the world in order to evaluate the intensity and duration of …

Although the prime causation of the Late Devonian Frasnian–Famennian (F–F) mass
extinction remains conjectural, such destructive factors as the spread of anoxia and rapid …

Variations in the concentration of redox sensitive elements combined with pyrite framboid
size data documented from a Marcellus Formation (Middle Devonian) core recovered from …

Abstract The Late Devonian (383-359 Ma) was a time of prolonged climate instability with
catastrophic perturbation of global marine ecosystems at the Frasnian-Famennian (FF) and …
