Re: [meteorite-list] The Eagle Has Landed, Oued Bourdim New Eagle Station Pallasite!
Hi all, Thank you to everyone that purchased specimens of my NEW Eagle Station Pallasite! Virtually all the larger specimens are sold - but, I just posted photos of some very nice smaller specimens. Many are priced at around the $100 range and some even less. Worth a look even if you're not in the mood to buy! http://www.mrmeteorite.com/ouedbourdimnewpes.htm BTW- I'll be selling out of Geoff Notkin's room this year so please stop by and take a look at these rare pallasites in person.

In meteorite classification five meteorites have to be found, so they can be defined as their own group. Currently only four Eagle Station type meteorites have been found. Thanks to Dr Laurence Garvie (ASU) Dr John Wasson (UCLA) Dr H. Chennaoui Aoudjehane and Dr Karen Ziegler (UNM) this was true until today! Oued Bourdim (provisional name) Is the fifth Eagle Station pallasite to be discovered and was just submitted for classification approval. Once this meteorite is classified Eagle Station will become a proper pallasite group! I purchased all there was - a total of nearly 400 grams - from Moroccan dealers over a three year period, in the form of small individuals. Already much of it has disappeared into Museum/University and private collections. I have only 140 grams of nice specimens for sale here. These individuals are small and range from about .250 grams to 9 grams, but just because these meteorites are small doesn't mean they're not awesome! This meteorite has everything going for it, beauty, rarity, and low TKW not to mention it has the distinction of being Eagle Station # 5 - finally making PES a proper pallasite group. Have you ever tried to purchase ANY Eagle Station Pallasite type? If so, you already know it's not easy to do - there is none on the private market for sale. It won't be long before this is all gone too! Institution trades are always welcome, but hurry while there is still a selection to choose from. Please check below for available specimens and prices. http://www.mrmeteorite.com/ouedbourdimnewpes.htm Weathering: medium Fa: 21.2 ±0.2 Classifier: L. Garvie, J. Wasson, K. Ziegler, H. Chennaoui Aoudjehane Type spec mass: 116.7 Type spec loc: ASU Main mass: ASU Finder: Brahim Oubadi Writeup history: (H. Chennaoui Aoudjehane, FSAC): During November 2007, Brahim Oubadi from Bouanane (south east Morocco, near Boudnib) was searching for meteorites near Oued Bourdim. He found many small pieces of a heavy rock (for its size) that looked different from the surrounding materials around 32° 00' 21.1N and 3° 14' 15.6 W. Over the next few years Mr. Oubadi found approximately 400 g. He sold the stones to a meteorite dealer in Boudnib, and they were subsequently sold at the Tucson Gem and Mineral show where they were nicknamed Boudnib. The meteorites were found on an old desert-varnish-covered wadi called Oued Bourdim. Writeup physical: Many small stones totaling 393 g: the largest are 48.9 g and 68.9 g, whereas the majority is 10 g in mass. Exterior of the stones is dark colored and the olivines are sand blasted with a waxy luster. Fusion crust largely absent, though there are a few remaining patches on the metal. Medium to low weathering. Writeup petrog: (L. Garvie, ASU). A 3 x 2 cm sawn surface of the 48.9 g stone shows 30 areal% metal. Olivine grains highly fractured, rounded and 1 cm across. Swathing kamacite to 1-mm thick and discontinuous. There are a few areas of swathing schreibersite to 0.5 mm thick. Ropey schreibersite also present within the swathing kamacite. Troilite rare, occurring as spheres to 1 mm in the olivine. The bulk of the metal has a martensite decomposition structure (Novotny et al., 1982), composed of Widmanstätten alpha platelets (typically 100 um long) in fine plessite matrix: schreibersite 10 to 50 um is common. The platelets are surrounded by taenite rims. Two chromite grains present. Excluding the 48.9 g stone, six additional stones were sectioned, polished, and etched - all showed metal with the martensite decomposition structure. Terrestrial Fe oxides locally replacing swathing kamacite and troilite. Reference: Novotny, P.M., Goldstein, J.I., and Williams, D.B. (1982) Analytical electron microscope study of eight ataxites.

[meteorite-list] Astronomers marshaled to help avert asteroid disasters
Hello Listers This are is a good read, its about Peter Jenniskens work and what he plans to do in the future. Enjoy Shawn Alan IMCA 1633 ebay store http://www.ebay.com/sch/imca1633ny/m.html Website http://meteoritefalls.com Astronomers marshaled to help avert asteroid disasters By David Perlman Updated 4:12 pm, Sunday, January 11, 2015 When Peter Jenniskens picked up a blackened rock in the Nubian desert six years ago, the Bay Area astronomer knew he held a chunk from an asteroid that had broken up in outer space and fallen to Earth. The rock, and 300 more fragments like it that Jenniskens collected in the desert, had been spotted by space watchers with telescopes as coming from a single “Near Earth Object.” NASA’s asteroid detectives spotted the complete asteroid in flight a full day before its pieces fell and guided Jenniskens, an astronomer and meteorite expert at the SETI Institute in Mountain View, to that precise desert area in Sudan. They had tracked its course, predicted its explosive impact when it hit the Earth’s atmosphere, determined where the blast debris would land and messaged their findings around the world. for more click here : http://www.sfgate.com/science/article/Astronomers-marshaled-to-help-avert-asteroid-6008369.php __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] A 2-KM-Wide Impact Crater Discovered in Antartica
You're probably right about them playing things to get more funding, they obviously should have better pics since they also did a ground expedition to the site: On a later trip to the crater site, the team led by Eagles mapped the ice surface in great detail with a laser-scanning instrument. They also surveyed the area with a radar instrument that penetrates the upper surface of the ice and snow. A number of smaller circular and sub-circular structures were spotted nearby on this trip. It is expected the team will publish their findings soon. They are hoping to hunt for meteorites around the site. Finding one would remove doubts.
