Perhaps the Meridiani structure is formed the same way as features on Mars discussed in this sci.astro thread but at a larger scale:

The first feature discussed here is at the link:

Mounds knobs.

(The links given in the first post of the thread are no longer active.)

However, is this feature with the circular rings a depression or a raised region in the MOC image?

In a later post to the thread I suggested an analogy to strandlines:

Ancient Shorelines on Fremont Island

This could work whether the feature(s) are depressions or raised regions.
I noted a similar image at the Martian polar layered deposits:

Additional Images of South Polar Layered Deposits near Proposed Mars
Surveyor '98 Landing Site,

Again I can't tell if this is a depressed or raised region.

I occurred to me that maybe the polar layered deposits are themselves strand or shorelines according to the theory of Baker et.al. of periodic oceans in the northern plains of Mars.
