  1. our conversation reminds me of this article
  2. History[edit] Aside from a very small deposit of telluric iron in Kassel, Germany, which has now been depleted, and a few other minor deposits from around the world, the only known major deposits exist in and nearby the area of Disko Bay, in Greenland. Found in the volcanic plains of basalt rock, the material was used by the local Inuit to make cutting edges for tools like knives and ulus. The Inuit were the only people to make practical use of telluric iron. In the late 1840s, Adolf Erik Nordenskiöld discovered large boulders of iron near the Disko Bay area of Greenland. Knowing that the Inuit had made tools from the Cape York meteorite, Nordenskiöld assumed that the metal was of meteoric origin, since both contain significant amounts of nickel and both had Widmanstatten structures. The existence of telluric iron was doubted by most scientists at the time, and few had reason to question Nordenskiöld's finding. In 1871, on his second expedititon to Greenland, Nordenskiöld collected three large samples of telluric iron, still believing them to be meteoric, and brought them back to Europe for further study. These samples can be found currently in Sweden, Finland and Denmark. A 25-ton block now rests outside of the Riksmuseum in Stockholm, a 6.6 ton block outside the Geological Museum in Copenhagen, and a 3-ton block can be found in the Museum of Natural History in Kumpula, Helsinki. Accompanying Nordenskiöld in 1871 was K. J. V. Steenstrup. Due to circumstances like the shape of the boulders, which often had sharp corners or jagged edges that are not characteristic of meteorites (which ablate considerably during atmospheric entry), Steenstrup disagreed with Nordenskiöld about the origin of the boulders, and set out on an expedition of his own in 1878. In 1879, Steenstrup first identified the type 2 iron, showing that it also contained Widmanstatten structures. Steenstrup later wrote about his finding, After the discovery in the grave, Steenstrup found many large outcrops of ferriferous basalt, containing the type 2 iron. Since the type 2 was located within volcanic basalt, Steenstrup was able to show that the iron was of terrestrial, or telluric, origin. In his treatise, Steenstrup added,
  3. I took a portion of the rock to the Earth science College in Minneapolis here this morning. They were very excited to get to study it he told me that it was definitely not man-made. A sample has already been sent to the University of Arizona and proven not to be a meteorite. The nickel content was too sparse being under 5% which would be in accordance with native iron in at about two and a half percent. I'm not computer savvy so I won't be able to transfer the link to the page on on the source to native or elemental iron in camron MO. but if you Google sources of native iron there are not too many and Cameron Missouri is one of them Which is a suburb of Kansas City where I found my sample but right on the border. I have sent along a photo of the Russian example that looks very similar to mine they all thought it was a mesosiderite. If it is native iron it will have all of the same properties as meteorites with the widmanstatten pattern of course there will be a few elemental defferences
  4. Of course I was stupid and clean the outside with wire brush years ago
  5. If I had not found it in Cameron Missouri were one of the examples of the Native iron from the United States is I would agree here are more pics
  6. Update I believe the picture of the rock I found is native iron as I found it in Cameron Missouri where there is a known example of native iron from there. It looks very similar to their native iron rock found in Russia recently in 2002 any opinions would be greatly appreciated
  7. That is good advice thank you I found this in my yard in Kansas City Missouri I was convinced it was a meteorite tested positive for nickel took it to a mineral and gem show and one of the meteorite men we're going to buy it send it to the lab but the nickel content was too sparse
  8. I am from Minnesota and will be working in Texas for the winter was going to try my luck at meteorite hunting in Texas but after reading in the Forum you all revising the gentleman to search for meteorites in Roosevelt County New Mexico my first week off I was thinking on going hunting between portals and Roswell maybe around Kenna have never been to the desert I plan on staying for a week just recently purchased a pulse induction metal detector any advice would be greatly appreciated
  9. Hi I'm from Minnesota and will be working in Texas for the winter just purchased a pulse induction metal detector and was going to hunt meteorites and I have not done it before and was just wondering if anyone can help me with a location will be in the Corpus Christi area
