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.

大火成岩省（LIP）代表了大量的主要是镁铁质火成岩的堆积，在地质学上的短时间内喷发和就位（Bryan和Ernst，2008年）。除了大量的熔岩外，LIPs还释放出大量的火山气体，这可能对地球的气候和生物圈产生破坏性影响（Ernst和Youbi 2017）。虽然有一个时间的相关性，并建议的因果关系，在地球历史上的全球气候变化和大规模灭绝事件的爆发，这些变化的程度似乎不同的LIPs之间。
