Constraining the timing of emplacement, duration and magma extrusion rates of large
igneous provinces is essential for evaluating their petrogenetic evolution and possible links …

We review the ages of Quaternary magnetic polarity reversals and magnetic excursions.
Improvements in radioisotopic 40 Ar/39 Ar dating of reversals and excursions reflect the use …

Efforts to date the oldest modern human fossils in eastern Africa, from Omo-Kibish,–and
Herto, in Ethiopia, have drawn on a variety of chronometric evidence, including 40Ar/39Ar …

Abstract The 40 Ar/39 Ar dating method is among the most versatile of geochronometers,
having the potential to date a broad variety of K-bearing materials spanning from the time of …

Late Cretaceous records of environmental change suggest that Deccan Traps (DT)
volcanism contributed to the Cretaceous-Paleogene boundary (KPB) ecosystem crisis …

The temporal link between large igneous province (LIP) eruptions and at least half of the
major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of …

Convergence between the Indian and Asian plates has reshaped large parts of Asia,
changing regional climate and biodiversity, yet geodynamic models fundamentally diverge …

Bolide impact and flood volcanism compete as leading candidates for the cause of terminal-
Cretaceous mass extinctions. High-precision 40Ar/39Ar data indicate that these two …

The geodynamic framework of the South China Craton in the Early Paleozoic and Early
Mesozoic has been modeled as developing through either oceanic convergence or …

Mass extinctions manifest in Earth's geologic record were turning points in biotic evolution.
We present 40Ar/39Ar data that establish synchrony between the Cretaceous-Paleogene …
