Timing and properties of latest Triassic 
CAMP basalts in the Argana basin (Morocco)
During Earth's history, five major mass extinctions are known to have occurred. One of these events occurred at ca. 200 Ma, near the transition from the Triassic to the Jurassic (Tr-J boundary). This event occurred contemporaneously or at least very close to the eruption of the large continental igneous province, the Central Atlantic magmatic province, or CAMP.

The temporal relationship of the Tr-J boundary and the province’s volcanism is the subject of many studies, and it is often suggested that the CAMP eruption has been the cause of the Tr-J mass extinction. 

From: Marzoli et al., Geology, 32(11), 973-976
Here, we use integrated stratigraphy of the continental deposits and the petrological properties of the basalts in the Argana basin to establish a correlation with other Tr-J boundary intervals, both in the USA (Newark) and the Tethys (Austria, Germany).
