The dawn of CAMP volcanism and its bearing on the end-Triassic carbon cycle disruption

Abstract:

The cause-and-effect relationship between the c. 201 Ma eruption of the Central Atlantic magmatic province (CAMP) and the end-Triassic abrupt climate change and mass extinction is at present based on controversial temporal correlations. Upper Triassic sedimentary strata underlying CAMP basalts in Morocco illustrate a clear mineralogical and geochemical fingerprint of early CAMP basaltic eruptions, namely unusually high contents of MgO (10-32 wt%) and of mafic clay minerals (11-84%). In the sa...
