Sequence of infilling events in Gale Crater, Mars: Results from morphology, stratigraphy, and mineralogy
Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine their origin. The sediment of Aeolis Mons is interpreted to be primarily air fall material such as dust, volc...
