Impact Earth: A review of the terrestrial impact record



An Early Jurassic age for the Puchezh‐Katunki impact structure (Russia) based on 40Ar/39Ar data and palynology

The Puchezh‐Katunki impact structure, 40–80 km in diameter, located ~400 km northeast of Moscow (Russia), has a poorly constrained age between ~164 and 203 Ma (most commonly quoted as 167 ± 3 Ma).

Did the Puchezh-Katunki Impact Trigger an Extinction?

The 80 km diameter Puchezh-Katunki impact crater is the only one of the six largest known Phanerozoic craters that has not been previously considered as a factor in a biotic extinction event. The age

The age of the Popigai impact event and its relation to events at the Eocene/Oligocene boundary

Ages ranging from the Late Cretaceous (∼65 Myr) to the Oligocene (∼29 Myr) have been reported for the 100-km-diameter Popigai impact structure on the Anabar shield, central Siberia. These ages

The Alvarez Impact Theory of Mass Extinction; Limits to its Applicability and the “Great Expectations Syndrome”

For the past three decades, the Alvarez impact theory of mass extinction, causally related to catastrophic meteorite impacts, has been recurrently applied to multiple extinction boundaries. However,

Time Scales of Critical Events Around the Cretaceous-Paleogene Boundary

Radiometric dating establishes the mass extinction that killed the dinosaurs as synchronous with a large asteroid impact between the Cretaceous-Paleogene boundary and associated mass extinctions with the Chicxulub bolide impact to within 32,000 years.

High-precision dating of the Kalkarindji large igneous province, Australia, and synchrony with the Early–Middle Cambrian (Stage 4–5) extinction

The voluminous Kalkarindji flood basalts erupted in Australia during the Cambrian and covered >2 x 10(6) km(2). New U-Pb and Ar-40/Ar-39 age data from intrusive rocks and lava flows yielded

Did the great dying of life take 700 k.y.? Evidence from global astronomical correlation of the Permian-Triassic boundary interval

The cause of the great Permian-Triassic (P-T) boundary mass extinctions remains unknown. A crucial step in identifying the cause involves a precise timing of the mass extinction interval (MEI) in
