i did not intent to specifically imply that it was limeston on mars , hence the "_" brackets around " limestone pavement "
i used that term only because it is the type of karst geology
i am most familar with
but as you will read - the bedrock must be quite soft and soluble - and prone to fractures which form the star points for errosion of the grykes
all karsts i am aware of form in sedimentary rock formations , harder igneous and volcanic rocks will be far more resistant to such selectibe and
localised erorions .
but as i pointed out - it was just a speculative observation which would require further evidence - both of the existance of further similar
parterning in adgacent photograps
and the analysis of the martian geology , i cannot google what type of rocks exact areas are , the classilfications are irritaingly generalised
and of course - it could just be another type of formation that has become " partially filled in " with sand or such
but IMHO a definite feature worthy of further study
hope that answers your querries
PS - i am neither a geologist or astronomer - just a mountaineering monkey
so all i have written is just my speculative opoinionate
