Well, it is a lake bed find, but that parallel shape is a coincidence on this one face. The back side of that slice (2mm away) looks like this: http://www.home.earthlink.net/~jlp3/images/M0301-7.jpg And the end that I cut off for the type sample didn't show it at all. It seems to be a local phenomenon. Contributing to my suspicion that it is a shock effect are pre-terrestrial (fused by the fusion crust where they meet it) cracks concentrically arranged farther out from the dark area. But I've been wrong before! Jeff The contents of this message may be privileged and confidential. Therefore, if this message has been received in error, please delete it without reading it.
