Osmium-isotope evidence for two pulses of increased continental weathering linked to Early Jurassic volcanism and climate change

Abstract:

Large Igneous Provinces (LIPs) are proposed to have caused a number of episodes of abrupt environmental change by increasing atmospheric CO2 levels, which were subsequently alleviated by drawdown of CO2 via enhanced continental weathering and burial of organic matter. Here, 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 potentially linked to the Karoo–Ferr...
