Takes about 2 seconds for any geologist worth a crap, even a 1st year college student for that matter, to ID Limestone.
The way the carvings intersect the solution holes makes it likely that the "runes" were carved much more recently than that rock was eroded.
Pics are tough to be sure from, but I'd bet it's fairly recent inscriptions on the rock.
