HiPOD: Mars and the Amazing Technicolor Ejecta Blanket
The colors observed in this picture represent different rocks and minerals, now exposed on the surface. Blue in HiRISE infrared color images generally depicts iron-rich minerals, like olivine and pyroxene. Lighter colors, such as yellow, indicate the presence of altered rocks.
@HiRISE
It is fascinating to see how much an infrared image can tell us about the geological history of the martian ejecta blanket!
What can the presence minerals like olivine and pyroxene tell us about the volcanic history?
or of possible past water activity in the Mare Serpentis region?
