U-Pb geochronology of the Deccan Traps and relation to the end-Cretaceous mass extinction
U-Pb zircon geochronology is applied to Deccan rocks and it is shown that the main phase of eruptions initiated ~250,000 years before the Cretaceous-Paleogene boundary and that >1.1 million cubic kilometers of basalt erupted in ~750,000 Years.

U-Pb constraints on pulsed eruption of the Deccan Traps across the end-Cretaceous mass extinction
According to this model, maximum eruption rates occurred before and after the K-Pg extinction, with one such pulse initiating tens of thousands of years prior to both the bolide impact and extinction.

The Late Campanian and Maastrichtian in northwestern Tunisia: palaeoenvironmental inferences from lithology, macrofauna and benthic foraminifera
Late Campanian through Maastrichtian sea-level changes are examined based on lithology, macrofossils and benthic foraminifera at the Elles and El Kef sections in Tunisia. Six major sea-level…
