Mantle plume found on Mars

January 24 , 2023 430 days 362 0
  • Researchers have discovered an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity.
  • The mantle plume is situated underneath a low-lying area called Elysium Planitia that lies north to the equator.
  • We have strong evidence for mantle plumes being active on Earth and Venus.
  • Mantle plumes are large blobs of molten rock that rise towards the surface from the interiors of a planet.
  • They push through the intermediate or mantle layers and accumulate at the base of the crust.
  • This geological phenomenon can be witnessed on Earth in Hawaii where the warm materials from the plume ooze out of fissures to create great volcanic plains.
