When you have a pot on the boil the crust is easy to discern: it's the stuff that doesn't always sink. That's easy to identify on Earth, but what does 'crust' mean on Mars?

This is a little clearer, even coming from Faux Scientist: Thank you stevesliva, a lot clearer even. Your quote suggest that previous meteorites from Mars are thought to have been ejected in the most major and powerful impacts on Mars and so came from some depth, whereas this one perhaps got started somewhere on the perimeter of one such, or even from a grazing impact. In some papers on Martian geology the authors have used the phrase 'The upper Martian crust" - I now tend to think that is what they intended to say in the Carnegie press release I linked at first. |
