Speaking of OOL, about a week or so since I read an article about a possible environment for OOL. A discovery on Greenland, in rock or sediment area of about the right age, consisting of some sort of mud. The article mentioned the probable characteristics of the environment at the time as more conducive to OOL than black smokers, they may be too hot for OOL processes.
I searched Science Daily earlier today but couldn't find it, don't think I saw it elsewhere.
Rocks have no biology.
