Dunno if **Bosda** was being ironic here, or if slate is possible under presumed past Martian conditions – But, someone with xenogeological knowledge: What sedimentary rocks are possible on a planet without open water? I’m sure Mars is well stocked with most grades of sediment, from cobbles down to clay-size particles – but (1) Would they cement/compress into rock in the absence of water? (2) What rocks? How would they differ from terrestrial rock forms? ---
