[meteorite-list] DIXON SPRINGS METEORITE REPORT AT LAST!

Why is it always the same story? The newspaper said the rock was examined at the Geology Department of Southern Illinois University in Carbondale, Illinois. After emailing the Geology Department office at SIU (and copying all 57 faculty and staff), I located the Geology Dept. faculty member who looked at the rock! Here's his description: A vesicular igneous-looking rock about the size of your fist. The surface vesicles are tabular and oriented in the same direction and up to 8 mm in size. The rock is dark outside and broken surfaces show a dark matrix with glassy inclusions. Some of the vesicles have a carbonized sustance in them. The rock has deposits of caliche (carbonates) and some algae growing on it. It has a low density and no attraction to a large conventional (iron) magnet. The boy and his father were nervous about him picking at the rock, so no cutting, filing, scraping, or corner grinding was done. He thought the boy's fall story was just that, a story, but he didn't say so. He did tell tham that his gut feeling was that it wasn't a meteorite but if they were convinced it was they should try the Field Museum in Chicago. He showed the boy the only meteoritic specimen that he had (a Canyon Diablo). So, at this point in the story, I'm thinking SLAG, when he said, "The word 'slag' crossed my mind." Dr. Richard Fifarek is an economic geologist specializing in hydrothermal depositation and stable isotope studies. This is why he gets stuck with everybody that comes to the university with a "meteorite" that they've found, because "My specialty is as close to meteorites as we get here, but I don't really know anything about meteorites." To his credit, soon Dr. Fifarek was asking me more questions about meteorites than I was asking him about the Dixon Springs rock. We ended by my agreeing to send him a set of criteria aimed at recognizing meteorites (and the procedure for the nickel test), which I have done. He says that 1 to 3 "meteorite visitors" show up on the Geology Department's doorstep every month, so a set of guidelines would help. He also asked if any of the people I knew that were interested in meteorites and were within reasonable distance of southern Illinois would be willing to provide contact information to him in case some stone that was a good candidate did turn up, so he could refer the finder to us. Well, YEAH, I think so. Rhett, Al, anyone? For all the griping I've heard about "geologists," I must say this was a pleasant and reasonable contact. I would imagine that most universities, particularly public ones, must have a similar experience with "meteorite visitors." Maybe we should help them out! Shame about the slag. Sterling K.
