I think a lot of craters (whatever their origin) on Mars formed simultaneously or nearly so. Often craters that appear to be the same age are seen in groups, sometimes in swaths that may cover thousands of kilometers.

In the example you refer to, my faulty eyes can only pick out about half a dozen impact craters. I am very dubious that the other formations resulted from impact, partly because of their sinuous shapes and "dual" natures.

I suspect that the majority of circular formations in that image are akin to maars such as we see here. The process of formation on Mars is probably not quite the same as on the Earth, but the resulting circular formation is very similar.

The stuff inside the formations, and the fan-like erosion pattern is fascinating. I haven't seen anybody discuss it.
