earthstory:Martian version of Yellowstone discovered …Mars is known for its pock-marked surface, the result of an ancient history of impacts forming meteor craters, but a paper published today in Nature has identified some of those craters as huge collapsed volcanic centres. After looking carefully at the “geomorphology” of a few craters, from remote sensing images of the surface, this new study claims that what have been assumed to be impact craters at some sites are, in fact, huge calderas - collapsed volcanoes. The interpretation is based on evidence of the shape, or lack. of the crater rim and lack of nearby splatter of material thrown up from a meteorite impact. The authors suggest that these features are vestiges of super volcanoes, akin to Yellowstone here on Earth. Keep reading -- source link
