"In 99% of all cases, sinkholes pop up in carbonate rocks (like limestone or dolomite) or evaporitic rocks (like gypsum or anhydrite)," the science news website ZME Science says.

Carbonate rock such as limestone should have formed in Mars' ancient past when it was warmer and wetter, but so far carbonate rocks have been few and far between in our exploration of the Red Planet.
