A chronology of the initiation dates of major continental flood basalt volcanism is established from published potassium-argon (K-Ar) and argon-argon (Ar-Ar) ages of basaltic rocks and related basic intrusions. The dating is therefore independent of the biostratigraphic and paleomagnetic time scales. Estimated errors of the initation dates of the volcanic episodes determined from the distributions of the radiometric ages are, approximately, plus or minus 4 percent. There were 11 distinct… 
The Age of Paran� Flood Volcanism, Rifting of Gondwanaland, and the Jurassic-Cretaceous Boundary
The Paran�-Etendeka flood volcanic event produced ∼1.5 x 106 cubic kilometers of volcanic rocks, ranging from basalts to rhyolites, before the separation of South America and Africa during the
Rapid Eruption of the Siberian Traps Flood Basalts at the Permo-Triassic Boundary
TLDR
Laser-heating 40Ar/39Ar data indicate that inception of Siberian Traps volcanism coincided with a profound faunal mass extinction at the Permo-Triassic boundary 249 � 4 million years ago; these data thus leave open the question of a genetic relation between the two events.
Gigantic volcanic eruptions and climatic change in the early Eocene
Abstract23 layers of altered volcanic ash (bentonites) originating from the North Atlantic Igneous Province have been recorded in early Eocene deposits of the Austrian Alps, about 1,900 km away from
Episodes of terrestrial geologic activity during the past 260 million years: A quantitative approach
Records of major geologic events of the past ∼260 Myr including: biologic extinction events, ocean-anoxic and black-shale events, major changes in sea level, major evaporite (salt) deposits,
Timing and duration of Mesozoic‐Tertiary flood‐basalt volcanism
A number of Eos articles [Courtillot and Cisowski, 1987; White, 1989] have addressed the hypothesized genetic link between flood-basalt volcanism and global faunal extinction events. This topic, and
Timing of the Ethiopian flood basalt event and implications for plume birth and global change
Continental flood basalts are often considered as fossil evidence of mantle plume heads impinging on the lithosphere, and have been related to continental breakup. Many of these flood basalts erupted
Gas Fluxes from Flood Basalt Eruptions
Subaerial continental flood basalt volcanism is distinguished from all other volcanic activity by the repeated effusion of huge batches of basaltic magma (∼102-103 km3 per eruption) over short

The Columbia River Basalts
TLDR
Between 17 million and 6 million years ago, 200,000 square kilometers of the American Northwest were flooded by basaltic lava that erupted through fissures in the crust up to 150 kilometers long to study mantle composition and the processes involved in the evolution of the earth's crust.
