[meteorite-list] Met Bulletin Update - Braunschweig Approved - April 23, 2013 Fall
Hi Bulletin Watchers, Lost in all of the excitement about Chelyabinsk was the 04-23-13 fall of the Braunschweig L6 meteorite in Germany. Link - http://www.lpi.usra.edu/meteor/metbull.php?code=58083 Write-up : Braunschweig52°13.548’N, 10°31.193’E Niedersachsen, Germany Fell: 2013 Apr 23, 02:05 a.m. Classification: Ordinary chondrite (L6) History: (R. Bartoschewitz, Bart) Erhard Seemann recognized a rock impact in the concrete pavement in his yard 3 m from his front door when he came home on April 23, 2013, in the morning. He documented his observation and collected the main fragments (~700 g) of the nearly complete crushed stone. A neighbor heard a strong hum followed by a loud crash that night at about 2:10 a.m. In the morning he found several small rock fragments (~50 g) in his gateway. In Ahlum village, Julian Mascow was surprised by a bright flare coming from the SE, ending in a short tracer just over his head. About 90 s later he was frightened by an explosion and ensuing rattling sound around him. Mark Vornhusen’s web camera documented the fireball from Vechta. When Rainer Bartoschewitz documented the meteorite impact, he discovered many further small fragments (~500 g) within 18 m of the others. Physical characteristics: (R. Bartoschewitz, Bart) One meteorite individual of about 1.3 kg broken into hundreds of small fragments after impacting concrete pavement. The biggest fragment, 214 g, stuck in the concrete making a 7 cm diameter, 3 cm deep impression. Other fragments were 30 g. The gray-white meteorite material is covered by a 0.4 mm thick dull black fusion crust with abundant 50 μm cracks. Magnetic susceptibility log χ = 4.75. Petrography: (R. Bartoschewitz, Bart) Recrystallized matrix of olivine, pyroxene (0.02-0.5 mm) and secondary feldspar bear poorly developed and deformed, dominantly barred olivine chondrules (0.5 to 15 mm, av. 1.5 mm), metal, troilite and chromite. Dark metal-troilite veins (50 µm) cross the meteorite. Olivine shows rather sharp extinction and irregular cracks. Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) olivine Fa24.3-26.0 (mean Fa25.2±0.40, n=33); Ca-poor pyroxene Fs20.8-21.7Wo1.0-1.8 (mean Fs21.3±0.24Wo1.6±0.20, n=12); Ca-rich pyroxene Fs8.1-8.8Wo44.4-45.2 (mean Fs8.4±0.40Wo44.7±0.35, n=4); feldspar An11-18Or 4-10, chromite Cr/(Cr+Al)=88.3, Fe/(Fe+Mg)=79.8. Kamacite Ni=4.7-6.2, Co=1.0; taenite Ni=20-34, Co=0.3-0.7 (all in wt.%) Classification: L chondrite (L6, S4, W0) Specimens: Main mass of about 700 g, E.

[meteorite-list] AD - NWA 6435 : Ureilite-like shiny Unbrecciated Diogenite with anomalously low REE !
Hello, a new diogenite added on my website today. First, better than a long story, a short video : http://www.youtube.com/watch?v=eBKZxHHEBRk Its realy looks-like an ureilite, but is a unbrecciated diogenite, metamorphic structure. Classified by Tony Irving, the REE content (Rare Earth Element, J-A Barrat personnal communication) is realy realy low if you compare to the other diogenites ! Diogenites, no heaviest REE under 0.01ppm : http://wwmeteorites.com/Ventes/NWA%206435/Diogenites-EMORB.gif NWA6435, no heaviest REE over 0.01ppm : http://wwmeteorites.com/Ventes/NWA%206435/REENWA6435.bmp Hard to picture as you can imagine, because all the beauty of this rock is in motion, but I prepared, polished all the specimens for the best shiny star effect !

Re: [meteorite-list] Met Bulletin Update - Braunschweig Approved - April 23, 2013 Fall
Well, there was quite some excitement among meteorite aficionados in Germany, but it's true that even in the German media this fall was almost not covered. It's good to have witnessed another German fall after more than a decade. It's unfortunate though that it shattered severely on impact.

[meteorite-list] The NWA 6435 name on MetSoc Database = Nightmare
Hello, because may of you asked about the statut of NWA 6435 on the Bulletin, here is the story (it have been discussed on the list with Norbert Kammel during the summer, the 9 jully, remember) : Maybe Jeff Grossman will explain this a different way (because at this time I have not understand all what happened), but I have a brachinite (now is the official NWA 5435) was for a time missnamed as NWA 6435 (this was the name I recieved from the classifier) ! So during a time, this meteorite had two provisionnal names (NWA 5435 and NWA 6435, close in look, easy mistake) ! At the same time the NWA 5435 number have been assigned too, to a stone of Norbert Kammel, a chondrite (this is what was discussed on the list on early july). The official for my brachinite was choosed as NWA 5435 (it is now OFFICIAL on the Bulletin), and the Norbert chondrite was reassigned as NWA 3999... last year, I submitted to Tony Irving a new stone (working name K091 for Kuntz091), after preliminary work on it of Jean-Alix Barrat, and the NWA 6435 was finally reassigned to this new stone, the unbrecciated diogenite I introduced today. OK for me this is a NIGHTMARE, I just did what I had to did, and now I have to writte here a real novel to explain what happen, and collectors possibly interesting in slices of this meteorite maybe will be suspicious ! I suppose I have to wait (month, years?) for this mistake was corrected on the Bulletin...

[meteorite-list] The NWA 6435 name on MetSoc Database = Nightmare
Hi Mendy and List, You inquired: Can someone please clarify why this is listed as a Brachinite instead of diogenite? Based on the composition being 90% olivine, should this not be listed as a dunitic diogenite? Because igneous-textured brachinites are olivine-rich rocks (79-93 vol% olivine) too. Looking forward to my little slice from Fabien and also looking forward to looking at it under the microscope. Maybe the size of the crystals can shed a bit more light on this enigmatic puzzle! But, whatever it is, it is an achondrite and it is beautiful, ... and thin sections may also be helpful in solving the riddle!

[meteorite-list] Curiosity Rover Inspects Pebbly Rocks at Martian Waypoint
http://www.jpl.nasa.gov/news/news.php?release=2013-288 NASA Rover Inspects Pebbly Rocks at Martian Waypoint Jet Propulsion Laboratory September 23, 2013 PASADENA, Calif. -- NASA's Mars rover Curiosity has resumed a trek of many months toward its mountain-slope destination, Mount Sharp. The rover used instruments on its arm last week to inspect rocks at its first waypoint along the route inside Gale Crater. The location, originally chosen on the basis of images taken from NASA's Mars Reconnaissance Orbiter, paid off with investigation of targets that bear evidence of ancient wet environments. We examined pebbly sandstone deposited by water flowing over the surface, and veins or fractures in the rock, said Dawn Sumner of University of California, Davis, a Curiosity science team member with a leadership role in planning the stop. We know the veins are younger than the sandstone because they cut through it, but they appear to be filled with grains like the sandstone. This Waypoint 1 site at an outcrop called Darwin is the first of up to five waypoint stops planned along the route of about 5.3 miles (8.6 kilometers) between the Glenelg area, where Curiosity worked for the first half of 2013, and an entry point to the lower slope of Mount Sharp, the mission's main destination. It is about one-fifth of the way along the route. The rover departed Waypoint 1 on Sept. 22 with a westward drive of about 75 feet (22.8 meters). Curiosity's science team planned the waypoints to collect information about the geology between Glenelg and Mount Sharp. Researchers want to understand relationships between what the mission already discovered at Glenelg and what it may find in the multiple layers of Mount Sharp. Analysis of drilled samples from veined Yellowknife Bay rocks in the Glenelg area provided evidence for a past lakebed environment with conditions favorable for microbial life. That means the mission has fulfilled its principal science goal. We want to understand the history of water in Gale Crater, Sumner said. Did the water flow that deposited the pebbly sandstone at Waypoint 1 occur at about the same time as the water flow at Yellowknife Bay? If the same fluid flow produced the veins here and the veins at Yellowknife Bay, you would expect the veins to have the same composition. We see that the veins are different, so we know the history is complicated. We use these observations to piece together the long-term history. Researchers set the top priority for the Waypoint 1 stop to be examination of a conglomerate rock outcrop, such as the pebbly sandstone. The veins were a bonus. As often happens, the closer we get, the more is revealed, said Kenneth Williford of NASA's Jet Propulsion Laboratory, Pasadena, Calif., a Curiosity science team member active in planning use of the rover's arm. The first specific location at Waypoint 1 for parking the rover and using the instruments on its arm was selected because images taken from nearly a football-field's length away showed outcrops that looked like conglomerate. Once Curiosity approached that location, new images showed the veins, so a second location for use of the arm was added to the plan. The rover spent one day using its arm at the first location and three more using its arm from the second location. On all four of these contact-science days, the investigations employed two instruments that are mounted in the turret at the end of the arm: the Alpha Particle X-ray Spectrometer, which identifies chemical elements present in a target, and the Mars Hand Lens Imager, which shows targets' textures, shapes and colors. Another device on the turret still holds some powder from a rock that Curiosity drilled into for sample collection at Yellowknife Bay four months ago. The laboratory instruments inside the rover have already analyzed portions from this sample, but researchers have options of many different instrument settings for doing further analyses. In weeks ahead, additional portions from the sieved powder being held in the arm may be delivered for those analyses. The powder is a precious scientific resource, but it also presents a special challenge for use of the spectrometer and camera on the turret. We don't want to put the turret in a position that gets the sample material onto the back side of the sieve, because that could clog pores in the sieve, said JPL's Matt Robinson, lead engineer for Curiosity's robotic arm operations. We have to consider the orientation of the turret during all of the moves for reaching the target, not just its orientation at the target. Despite this challenge, the team used the arm instruments intensively at Waypoint 1. On Sept. 19, the rover examined five targets with the spectrometer and camera on the arm. The next day, from the same location, it examined three more. The team did leave some potential targets unexamined, to hasten back on the drive to Mount Sharp, as planned. There's a trade-off, Williford said, between
Re: [meteorite-list] The NWA 6435 name on MetSoc Database = Nightmare
Carl, I completely agree. Not being intimately involved in the process, I will offer what may be considered a simplistic fix, but one I hope one that is taken to heart. I see two broad categories of meteorites from a classification perspective: standard and unusual. If a stone is analyzed by a known meteoriticist with a record of solid classifications and that stone is something similar to other specimens, like a diogenite for example, then the classification should be immediately published. No provisional classification would be needed. If a stone is analyzed by a known meteoriticist with a record of solid classifications and that stone is turns out to be something unusual like NWA 7034, then when the initial analysis is complete, it should be published with all available data and with its proposed classification - even if it is something new. This new method would allow scientists to publish papers and enable a greater level of cooperation amongst themselves as well as aid the dealers and collectors. The meteorite classification would be labeled as proposed or something else deemed suitable. As science takes its course, then the classification might change but at least basic information would not. This would also be useful to enable other meteoriticists to analyze paired specimens and determine if a stone they did not originally classify is, in fact, a pairing. This process would streamline classifications, allow science to proceed unimpeded and reduce overall time and cost. I hope that what I propose is not shot down because one detail may not work. I do hope that we come up with ideas on how to make this or a similar idea feasible to the benefit of the entire meteorite community.

So during a time, this meteorite had two provisionnal names (NWA 5435 and NWA 6435, close in look, easy mistake) ! At the same time the NWA 5435 number have been assigned too, to a stone of Norbert Kammel, a chondrite (this is what was discussed on the list on early july). The official for my brachinite was choosed as NWA 5435 (it is now OFFICIAL on the Bulletin), and the Norbert chondrite was reassigned as NWA 3999... last year, I submitted to Tony Irving a new stone (working name K091 for Kuntz091), after preliminary work on it of Jean-Alix Barrat, and the NWA 6435 was finally reassigned to this new stone, the unbrecciated diogenite I introduced today. OK for me this is a NIGHTMARE, I just did what I had to did, and now I have to writte
[meteorite-list] whats the 1st meteorite from The Nininger Collection of Meteorites?
Hello Listers I have a question about the Nininger meteorite collection. I have seen some of the meteorites with numbers only and some with numbers and letters, why is that I am assuming 1a or 1 would be the first meteorite inducted into his collection. Does this mean that's the first one he owned? Lastly, what was the first meteorite put into The Nininger Collection of Meteorites?
