A new rock in Algeria sheds light on the history of our little brother, Mars.
As announced on
“An unusual meteorite found in Algeria in 2012 has given scientists information about volcanic activity on Mars, and it’s not like anything we’ve ever seen on Earth. Analysis of the 6.9-ounce meteorite by an international team of scientists, has helped determine that sometime in its 4.5 billion-year history, Mars had a single volcano that erupted continuously for more than 2 billion years.”
Earth has plate tectonics, which constantly shuffle the Earths surface, like pieces of jigsaw being moved around a table. This regenerates the surface of the Earth every few thousand years of so, and so Earth volcanoes can’t get much older than that. But on Mars there is very little tectonics, and probably none at all. So a volcano can just keep going and going. The mystery of the Mars rock, solved by old volcanism
