When I first examined the stone I was not even sure it was meteoritic but it was magnetic and dense. It reminded me of iron shale I had seen in other iron type meteorites so I broke off a small piece and diamond lapped it. When I saw a few elemental metal flakes imbedded in the shale, I knew with 90% certainty it was a weathered iron meteorite so I sent a piece in for classification. Here are a few images with explanations. This image shows where weathering has delaminated the crystalline structure. If you look carefully you can see 10 mm sized bands forming a triangular pattern. What is interesting is that the original Old Woman meteorite has a 10 mm bandwidth making it a coarsest octahedrite. The reason this specimen is more weathered than the original find is that it was found at a lower elevation where moisture is more prevalent. Freshly found Old Woman IIAB Iron meteorite, image one: http://themeteoritesite.com/oldwoman.jpg The second image shows the side with less weathering and more elemental iron: http://themeteoritesite.com/Oldwoman2.jpg I hope you enjoyed the images and will take any advice on what to do with this very special meteorite. Should I donate it and if so where? ------------------------------------ Adam Hupe The Hupe Collection Team LunarRock IMCA 2185 raremeteorites_at_comcast.net Received on Thu 05 Aug 2004 06:09:44 PM PDT |
