A singular occasion in Earth's historical past happened approximately two hundred million years in the past, as rifting of the biggest and most up-to-date supercontinent used to be joined via basaltic volcanism that shaped the main vast huge igneous province (LIP) recognized. A profound and common mass extinction of terrestrial and marine genera happened at concerning the similar time, suggesting a causal hyperlink among the organic transitions of the Triassic-Jurassic boundary and large volcanism. a chain of stratigraphic, geochronologic, petrologic, tectonic, and geophysical reviews have resulted in the id of the dispersed remnants of this imperative Atlantic Magmatic Province (CAMP) at the rifted margins of 4 continents. present discoveries are regularly interpreted to point that CAMP magmatism happened in a relative and absolute period of geologic time that used to be short, and element to mechanisms of beginning and international environmental results. simply because a lot of those discoveries have happened in the prior a number of years, during this monograph we summarize new observations and supply an updated evaluation of the province.
