Yes, I got that the first reading, and my comment was in reference to currently not being weathered AKA exposed to the elements which would detiorate stone.Read first.
Meaning very weathered from long exposure to rain and sun.
I'm not sure why it deteriorates but it has small tiny pits forming in the face. I would guess it's the minerals in the soil, probably very alkalitic. I've only ever seen that happen a few times but it usually only happens right at the surface where the patina is the thickest. I've never seen it happen on pieces without heavy patina or fossiliferous inclusions.
Some of the minerals in the ground up here can really be tough on KRF. I don't know what minerals do it though. If you have Jeb Taylor's book he has a picture of a 3" Knife River Flint Folsom that was found about 10 miles south of where this one was....it is heavily patinated and also has the same deterioration as can be seen starting on this point.Yes, I got that the first reading, and my comment was in reference to currently not being weathered AKA exposed to the elements which would detiorate stone.
I could see if it was a bone or something that is very susceptible to temp and humidity.
The question remains.
