Carbon-cycle changes during the Toarcian (Early Jurassic) and implications for regional versus global drivers of the Toarcian oceanic anoxic event
(Elsevier Science, 2020-10)
The Early Jurassic Toarcian oceanic anoxic event (T-OAE) is characterized by an extinction event, a major sea-level rise, enhanced marine primary productivity, elevated seawater temperatures, widespread deposition of ...
Episodic Jurassic to Lower Cretaceous intraplate compression in Central Patagonia during Gondwana breakup
(Pergamon-Elsevier Science Ltd, 2016-12)
From Lower Jurassic to Lower Cretaceous, several intraplate compression events affected discrete sectors of Central Patagonia, under a general context of crustal extension associated with Gondwana breakup. This was ...
