This odd cabinet-sized specimen consists of a pale brown host rock that is partly coated by several patches of extremely fine, fibrous Mordenite crystals. These crystals are much finer than human hair and are so thin that they look like cotton wool or spider webs. They are flexible, and though there is some noticeable damage to a few of the patches, individual fibers are far too small to study even under 15x magnification. They grow out of patches of more massive, white material that is most likely more Mordenite, and there are small spots of a pale green coloration that are evidence of a thin layer of unknown material between the massive layer and the base rock.
