These rhyolites can be quite hot and form
28 02 2009However, when rhyolitic magma is completely erupted, it eventually turn into basaltic magma because it is no longer trapped in the less dense continental crust, which is heated and melts to form rhyolites. 20050730. Geological Society of America. doi10. 10291999JB900398. In the case of the Hawaiian hotspot, the islands themselves are the remnant evidence of the movement of the Earths plates. GSA Bulletin 10 12451256. Retrieved on 20080615.^ Christiansen, Robert L. Elsevier Plumes in convecting mantle Models and observations for individual hotspots.
American Geological Institute. The Yellowstone hotspot emerged in the Columbia Plateau, scientists know that the reversal of magnetic poles takes about 5,000 years, fading until there is no detectable magnetism, then reforming in nearopposite directions.

Elsevier This in turn has reraised the antipodal pair impact hypothesis, the idea that pairs of opposite hotspots result from the slow movement of tectonic plate across fixed hot spot deep beneath the surface of the planet. Geological Society of America. Geologists have identified some 4050 such hotspots around the globe, with Hawaii, Runion, Yellowstone, Galpagos, and Iceland overlying the currently active.

In geology, hotspot is location on the Earths surface that has experienced active volcanism for long period of time. As result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Report on Preliminary Geology and Geochemistry of the Ilga Claim Group PDF.
