Spirit Sol 588 "Microscopic" Images (http://marsrovers.jpl.nasa.gov/gallery/all/spirit_m588.html)

What is Spirit looking at here?

In particular I see clear fine layering here. In particular this image (http://marsrovers.jpl.nasa.gov/gallery/all/2/m/588/2M178563924EFFAE03P2957M2M1.HTML) and this image (http://marsrovers.jpl.nasa.gov/gallery/all/2/m/588/2M178564120EFFAE03P2977M2M1.HTML).

Is it a natural feature of the rock or is an artifact created by a worn-down RAT?

I think the corduroy parallel lines in the regolith are just from the prevailing wind. There's lots of similar dust around at the summit, and the preceding mossbauer press images (like this (http://origin.mars5.jpl.nasa.gov/gallery/all/2/m/588/2M178563052EFFAE03P2956M2M1.HTML)) show similar. The front hazcam image (http://origin.mars5.jpl.nasa.gov/gallery/all/2/f/588/2F178564262EFFAE03P1110L0M1.HTML) shortly after that MI (http://origin.mars5.jpl.nasa.gov/gallery/all/2/m/588/2M178564010EFFAE03P2977M2M1.HTML) shows the instruments near some wheel tracks, perhaps accounting for the broken-up look. (The front hazcam before, probably just after it was doing the doughnut-shaped mossbauer impressions, is here (http://origin.mars5.jpl.nasa.gov/gallery/all/2/f/588/2F178563406EFFAE03P1110R0M1.HTML).)
