Can material that these were made from be tested to determine what part of the country they could be from? I have been in contact with the widow that had some of her husbands collection to me. She messaged me and has more items that she will sell me. She said a while back he loved to hunt for meteorites and other relics. He hunted mostly in Ohio, but he and a friend had hunted in different areas of New Mexico, Arizona, Texas, and Florida. They had followed construction sites to get their relics. She said she has some suspected meteorites that are marked as such, but is not sure if that is what they are? If I get lucky enough to but them, I will post them on the forum. In the mean time, I need to get some good information on this stuff. Some or all look like maybe they are made of sandstone and a couple pieces are of clay. Thanks for looking at these.
