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 …

Temporal correlation between some continental flood basalt eruptions and mass extinctions
has been proposed to indicate causality, with eruptive volatile release driving environmental …

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 …

The breakup of the former Pangea supercontinent culminated in the modern drifting
continents. Increased rifting caused the establishment of the Atlantic Ocean in the middle …

To discover interordinal relationships of living and fossil placental mammals and the time of
origin of placentals relative to the Cretaceous-Paleogene (K-Pg) boundary, we scored 4541 …

Past interglacial climates with smaller ice sheets offer analogs for ice sheet response to
future warming and contributions to sea level rise; however, well-dated geologic records …

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 …

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