I am new to rockhounding and metal detecting. I'm trying to learn as I go.. i came across these. Found in Pennsylvania
Thank you very much.. I thought serpentine but wasn't positive. Do you mean just the vein on the right looks like iron pyrite? If so do you know what the splintered rock it's running through is? I am on the Maryland/Pennsylvania line but in Chester County. My propert is very close to Barrens here.It looks like the one on the left is serpentine and the one on the right is iron pyrite.
My guess would be that would put your find location in the Serpentine Barrens near the Maryland/Pennsylvania state line. Probably somewhere near Cornwall in Lebanon County?
