Impact of Paraná-Etendeka volcanism on the Early Cretaceous climate

大型火成岩省(LIP)主要是镁铁质火成岩的大量堆积，在地质上很短的时间内喷发和侵位(Bryan和Ernst 2008)。嘴唇，除了大量的熔岩外，还释放出大量的火山气体，这可能对地球气候和生物圈产生毁灭性的影响(Ernst和Youbi 2017)。尽管嘴唇的喷发与全球气候变化时期和地球历史上的大灭绝事件之间存在着时间上的相关性和暗示的因果联系，但这些变化的程度似乎在嘴唇之间有所不同。

Large Igneous Provinces (LIPs) represent voluminous accumulations of mainly mafic igneous rocks, erupted and emplaced in a geologically short duration (Bryan and Ernst 2008). LIPs, in addition to the large volumes of lava, release enormous amounts of volcanic gases, which can have devastating effects on the Earth's climate and the biosphere (Ernst and Youbi 2017). Although there is a temporal correlation, and a suggested causal link, between the eruption of LIPs and periods of global climate change and mass extinction events in the Earth's history, the extent of these changes seems to vary between LIPs.
