Correlation of Hot-spots With Large Igneous Provinces
The early volcanic activity of major hotspots, postulated to result from deep mantle plumes, is frequently accompanied by flood basalts. These flood basalt eruptions have resulted in large accumulations of basaltic lavas emplaced at a rate greatly exceeding that seen in contemporary volcanic processes. Continental rifting commonly follows flood basalt volcanism. Flood basalt provinces may also occur as a consequence of the initial hot-spot activity in ocean basins as well as on continents. It is possible to track the hot spot back to the flood basalts of a large igneous province; the table below correlates large igneous provinces with the track of a specific hot spot.
| Province | Region | Hotspot | Reference |
|---|---|---|---|
| Columbia River Basalt | Northwestern USA | Yellowstone hotspot | |
| Afro-Arabia | Yemen-Ethiopia | ||
| North Atlantic Igneous Province | Northern Canada, Greenland, the Faeroe Islands, Norway, Ireland and Scotland | Iceland | |
| Deccan Traps | India & southern Pakistan | Reunion Island | |
| Rahjamal Traps | Eastern India | Ninety East Ridge | |
| Ontong-Java Plateau | Pacific Ocean | Louisville hotspot | |
| Paraná and Etendeka traps | Brazil–Namibia | Tristan da Cunha | |
| Karoo-Ferrar Province | South Africa, Antarctica, Australia & New Zealand | Marion Island | |
| Caribbean large igneous province | Caribbean-Colombian oceanic plateau | Galápagos hotspot |

Famous quotes containing the word large:
“The educational system in large countries will always be utterly mediocre, for the same reason that the cooking in large kitchens is mediocre at best.”
—Friedrich Nietzsche (1844–1900)
