Did they specifically identify perchlorate, or is that inferred from the chlorinated hydrocarbons?
Would water percolating through rocks really deposit (very soluble) perchlorate, or wash it away? AFAIK, rocks on Earth do not contain substantial perchlorate. HCl was mentioned, so maybe that was the source of the chlorination? Or maybe perchlorate from some of the soil left over from Rocknest? At least now the level of chlorinated hydrocarbons is way above the blank background. |
