Any idea?

Found this where they are excavating probably pretty common rock?

Granitoid. Looks kinda like a porphyry texture..

Ontario Canada? Likely Gowganda tillite...looks a little atypical but I'm in northern Michigan and there is a lot of that stuff here as glacial erratics brought here from the Canadian Shield.

Otherwise, yeah, granitoid...or undefined tillite

Appreciate the help guys.
Didn't think was anything too special just haven't came across one around here...

Thanks will do some research with my kids later they enjoy to learn and search for new stuff.
Big help again appreciate it
