The rock in the lower right corner looks similar to the rocks at the Opportunity site:

Or perhaps it could be just pumice:

Well the rock at the top looks to have striations also, wouldn't be a bad thing, sedimentary rock laid down and then jumbled after the impact.

Top left corner rock looks layered as well.

More evidence of water activity?

Where was the rover when this was taken?

If it was near the large crater, perhaps these rocks were ejected from the crater, and perhaps could be sedimentary.

If they were sedimentary, though, the team should have noticed that and looked at them with the instruments.

Near Missoula, if this (http://qt.exploratorium.edu/mars/spirit/navcam/2004-04-23/2N135694490EFF3100P1833L0M1.JPG) roughly contemporaneous photo is any indication.
