TLDR
Aptian-Albian carbon isotope records of marine carbonate, marine organic carbon, and terrestrially photosynthesized carbon as a 3-5% negative excursion were recorded in the early Aptian (ca. 117 Ma) CO 2 clathrates as mentioned in this paper.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.
Journal ArticleDOI
Evidence for rapid climate change in the Mesozoic-Palaeogene greenhouse world
TL;DR: In both the early Toarcian and early Aptian cases, the negative carbon–isotope excursion precedes global excess carbon burial across a range of marine environments, a phenomenon that defines these intervals as oceanic anoxic events (OAEs).
Journal ArticleDOI
Frontiers in large igneous province research
TL;DR: The most promising Archean LIP candidates (apart from the Fortescue and Ventersdorp platformal flood basalts) are those greenstone belts containing tholeiites with minor komatiites.

Recognizing mantle plumes in the geological record
TL;DR: In this article, geochemistry and isotopes can be used to test and characterize the plume origin of a large igneous province (LIP), dominated in the Phanerozoic by flood basalts and in the Proterozoic by the exposed plumbing system of dykes, sills, and layered intrusions.

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.

Carbon Isotope Discrimination and Photosynthesis
TL;DR: In this article, the physical and enzymatic bases of carbone isotope discrimination during photosynthesis were discussed, noting how knowledge of discrimination can be used to provide additional insight into photosynthetic metabolism and the environmental influences on that process.

Magmatism at rift zones: The generation of volcanic continental margins and flood basalts
Robert S. White,Dan McKenzie +1 more
TL;DR: In this paper, the authors show that the production of magmatically active rifted margins and the effusion of flood basalts onto the adjacent continents can be explained by a simple model of rifting above a thermal anomaly in the underlying mantle.

Geocarb III: A Revised Model of Atmospheric CO2 over Phanerozoic Time
TL;DR: In this article, the GEOCARB model has been updated with an emphasis on factors affecting CO2 uptake by continental weathering, including the role of plants in chemical weathering and the application of GCMs to study the long-term carbon cycle.
