Yea!...And that creates a puzzle.
From what I've read olivine is destroyed in a large body of sitting water....And then there are the abundances of salt in the soil.
They seem to contradict each other.
Perhaps the finely fragmented olivine was blasted out of a distant dry-crater,
long after any "hypothetical" body of water had disappeared from Gusev Crater. That might explain the salts.
If you're interested: The three peaks to the left of silicon are
sodium, magnesium, and aluminum. Sodium is the one of interest to me.
WEIGH IN, NICK!! WE NEED YOU!!!
cheers.
