Flood basalt - Wikipedia
WEBA flood basalt (or plateau basalt[1]) is the result of a giant volcanic eruption or series of eruptions that covers large stretches of land or the ocean floor with basalt lava. Many flood basalts have been attributed to the onset of a hotspot reaching the surface of the Earth via a mantle plume. [2]
Columbia River Basalt Group Stretches from Oregon to Idaho
WEBThe Columbia River Basalt Group (CRBG) is the youngest, smallest and one of the best-preserved continental flood basalt province on Earth, covering over 210,000 km2 of mainly eastern Oregon and Washington, western Idaho, and part of northern Nevada.
Flood Basalt - an overview | ScienceDirect Topics
WEBFlood basalt is formed by an eruption or series of eruptions of large volcanic episodes that cover vast stretches of land or ocean floor with flows of mafic igneous rocks (basalt lava flows). A flood-basalt province is popularly known as Trap (Deccan Traps in India).
Flood Basalts | Volcano World | Oregon State University
WEBFlood Basalts. Flood basalts are yet another strange type of "volcano." Some parts of the world are covered by thousands of square kilometers of thick basalt lava flows - individual flows may be more than 50 meters thick, and individual flows extend for …
Rapid eruption of the Columbia River flood basalt and ... - AAAS
WEBSep 19, 2018 — The Columbia River Basalt Group (CRBG) is the youngest, smallest, and best-preserved continental flood basalt. It erupted ~210,000 km 3 of lava in the Pacific Northwest, United States, between ~17 and 5 million years (Ma) ago.
Flood Basalts and Mass Extinctions - Annual Reviews
WEBFlood basalts, the largest volcanic events in Earth history, triggered dramatic environmental changes on land and in the oceans. Rapid volcanic carbon emissions led to ocean warming, acidification, and deoxygenation that often …
Origin of Columbia River flood basalt controlled by ... - Nature
WEBFeb 15, 2012 — The origin of the Steens–Columbia River (SCR) flood basalts, which is presumed to be the onset of Yellowstone volcanism, has remained controversial, with the proposed conceptual models...
Flood Basalts and Hot-Spot Tracks: Plume Heads and Tails | Science …
WEBContinental flood basalt eruptions have resulted in sudden and massive accumulations of basaltic lavas in excess of any contemporary volcanic processes. The largest flood basalt events mark the earliest volcanic activity of many major hot spots, which are thought to result from deep mantle plumes.
Flood basalts | AMNH - American Museum of Natural History
WEBAmong the major outpourings of lava are the huge plains known as flood basalt provinces. The Siberian basalts, the Deccan traps of India, and the Karoo basalts of southern Africa are among the largest of these on land; similar vast plains exist in the ocean basins as well.
Flood basalt - SpringerLink
WEBFlood basalts form thick piles of basaltic lava flows of vast areal extent (often exceeding 100,000 km 2) and volume (exceeding 100,000 km 3), usually on continental crust. Individual flows may be very voluminous, both exceeding 20 m in thickness, and covering more than 1,000 km 2 (Table 1).
