Marine 187Os/188Os isotope stratigraphy reveals the interaction of volcanism and ocean circulation during Oceanic Anoxic Event 2
TLDR
In this paper, high-resolution osmium (Os) isotope stratigraphy across the Cenomanian-Turonian Boundary Interval from 6 sections for four transcontinental settings has produced a record of seawater chemistry that demonstrates regional variability as a function of terrestrial and hydrothermal inputs, revealing the impact of palaeoenvironmental processes.About:

Large Igneous Provinces
TL;DR: Large igneous provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100,000 km3, and often above 1 million km3 as discussed by the authors.

How Large Igneous Provinces affect global climate, sometimes cause mass extinctions, and represent natural markers in the geological record
TL;DR: In this paper, a mass extinction link between large Igneous provinces (LIPs) and global climate change is investigated. But the specific effects, their severity, and their time sequencing are specific to each LIP.

TL;DR: In this article, the authors explored the use of mercury as a possible direct link between the Karoo-Ferrar LIP and the coeval Toarcian OAE (T-OAE).

TL;DR: In this paper, the sedimentary records of two such episodes of environmental change, the Toarcian oceanic anoxic event (T-OAE) and preceding Pliensbachian-Toarcian (Pl-To) event (both possibly linked to the Karoo-Ferrar LIP), are investigated using a new suite of geochemical proxies that have not been previously compared.
