A few ideas after brainstorming a bit ... what brain? :-)
Mike B. writes: " Iowa has three official chondrites to its name prior to his passing. Marion, 1847 (L6), Homestead, 1875 (L5) and Forest City, 1895 (H5)" *If* it's Marion, you might find veins because Marion is described as having veins. *If* it's Homestead, it should be brecciated and severely shocked (S4). *If* it's Forest City, it should also show brecciation. Hmm, Homestead and Forest City, ... both brecciated :-( But: Measuring the diameters of the chondrules might help here as Forest City chondrules (H5) should be smaller than Homestead chondrules (L5). By the way, just in case your thin section should contain copper, ... Homestead is described as containing copper.
