New paper in Nature Communications : the link between CAMP and the end-Triassic mass extinction
New high-precision U-Pb ages of zircon from mafic igneous rocks of the Central Atlantic Magmatic Province (CAMP) were published in a new article in Nature Communications by Davies et al. The study reveals that part of the sills, dykes and intrusions of the CAMP predate the end-Triassic extinction event and thus qualify as triggers for the severe environmental crisis that has erased around 60% of all species living at that moment. Among these intrusions is a sill crosscutting coal and oil bearing strata of the Amazonian basin in Brazil, corroborating hypotheses that release of thermogenic CO2 played a paramount role in establishing the lethal climatic conditions.
