| 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. |

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).
