Carl, I'm curious. Would cutting the stone in distilled water affect the oxygen isotope ratios? If I remember correctly that was one indicator that was used as proof of water on Mars. Thank you!

Re: [meteorite-list] AD - Black Beauty
Hi Mendy, No, cutting in distilled water has no effect on the oxygen isotopes of the bulk rock, nor does it affect the hydrogen isotopes of the martian water in NWA 7034. Simply drying the slice after cutting is all you need to do. Remember, this is a desert meteorite, exposing it to distilled water for a few minutes at room temperature in a saw is nothing compared to many years of exposure to the elements in the Sahara. Nonetheless, NWA 7034 is relatively unweathered meteorite, it is amazingly hard and solid, tough to chip or break. I attribute this to its welding during volcanoclastic eruption and/or impact. The only weathering products we have identified in NWA 7034 are some fine calcite veins that can be traced back to the surface. These are found primarily in the outer edges, and are less common the deeper you go into the 320 g main mass. On the other hand, we are planning to break some material from the deep interior, without water, to search for any water soluble minerals that may be affected by water cutting. Lots of work still to do! -- mainly because every slice Black Beauty shows something new. In my opinion, this rock is actually a volcanic conglomerate, that has picked up pebbles and soil particles during its flow over the martian surface or during impact. So, in a way each new piece of Black Beauty may reveal something more about Mars. I'll stop there, as you can see asking me about NWA 7034 is dangerous -- especially if you are not ready for a lengthy reply! Carl Agee -- Carl B.

Re: [meteorite-list] AD - Black Beauty
Hi Jason, I wasn't aware that there were slices of Black Beauty cut by anyone other than Matt Morgan or myself. We both used distilled water. As you can imagine, I am much more interested in Black Beauty science than the business end -- I'll let others worry about the market value. What's that slogan again in the VISA ads?

[meteorite-list] Near-Earth Asteroid 2012 DA14 Makes Preview Appearance
http://www.jpl.nasa.gov/news/news.php?release=2013-060 Near-Earth Asteroid Makes Preview Appearance Jet Propulsion Laboratory February 14, 2013 [Animation] This animated set of three images depicts asteroid 2012 DA14 as it was seen on Feb. 14, 2013 This animated set of three images depicts asteroid 2012 DA14 as it was seen on Feb. 14, 2013, at a distance of 465,000 miles (748,000 kilometers). The animation was created by astronomers at the Remanzacco Observatory in Italy using observations obtained remotely from the Faulkes Telescope South in Siding Springs, Australia. Image Image credit: LCOGT/Faulkes - Full image and caption http://www.nasa.gov/mission_pages/asteroids/multimedia/asteroid2012da14i.html Like trailers for the coming attraction, new images show asteroid 2012 DA14 on its way to a record-close approach to Earth on Feb. 15. One image, taken by amateur astronomer Dave Herald of Murrumbateman, Australia, on Feb. 13, shows the asteroid as a tiny white dot in the field of view. Another set of animated images, obtained by the Faulkes Telescope South in Siding Springs, Australia, on Feb. 14, and animated by the Remanzacco Observatory in Italy, shows the asteroid as a bright spot moving across the night sky. These are some of many images that may be taken of the asteroid during its close - but safe - encounter with Earth. It will be observed by numerous optical observatories worldwide in an attempt to determine its rough shape, spin rate and composition. NASA scientists will use NASA's Goldstone Solar System Radar, located in California's Mojave Desert, to take radar images of the asteroid to determine its precise size and shape on Feb. 16, 18, 19 and 20. The NASA Near Earth Object Observation (NEOO) Program will continue to track the asteroid and predict its future orbit. Asteroid 2012 DA14 is about 150 feet (45 meters) in diameter. It is expected to fly about 17,200 miles (27,000 kilometers) above Earth's surface at the time of closest approach, which is about 11:25 a.m. PST (2:25 p.m. EST) on Feb. 15. This distance is well away from Earth and the swarm of low Earth-orbiting satellites, including the International Space Station, but it is inside the belt of satellites in geostationary orbit (about 22,200 miles, or 35,800 kilometers, above Earth's surface.) The flyby of 2012 DA14 is the closest-ever predicted approach to Earth for an object this large. The NASA Near Earth Object Observation (NEOO) Program detects and tracks asteroids and comets passing close to Earth using ground- and space-based telescopes. The network of projects supported by this program, commonly called Spaceguard, discovers these objects, characterizes a subset of them and plots their orbits to determine if any could be potentially hazardous to our planet. The Near-Earth Object Program Office at JPL manages the technical and scientific activities for NASA's Near-Earth Object Observation Program of the Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena. The NEOO Program Office performs more precise orbit determination on the objects, and predicts whether any will become an impact hazard to the Earth, or any other planet in the solar system.

[meteorite-list] At The Mouth of the Red Valley (Mars Express)
http://www.esa.int/Our_Activities/Space_Science/At_the_mouth_of_the_red_valley At the mouth of the red valley European Space Agency 14 February 2013 [Image] ESA's Mars Express took a high-resolution stereo image on 13 January of the southeast corner of the Amenthes Planum region on Mars, near to Palos crater and the mouth of a well-known sinuous valley, Tinto Vallis. At the bottom-centre of the full-colour image above, and up close in the first perspective image, is a nearby shorter and wider valley, which is fed by a number of tributaries before it joins the mouth of Tinto Vallis as both empty into Palos crater, just off the bottom of the image. The 190 km-long Tinto Vallis is seen in the context image and is named after the famous Rio Tinto river in the Andalucia region of Spain. It is believed to have formed around 3.7 billion years ago, during the early history of Mars. [Image] Valley feeding Palos Crater The network of shorter valleys shown in the first perspective image is thought to have formed through volcanic activity melting subsurface ice and liberating water to the martian surface via seeps and springs. If underground water emerges to the surface from the side of a slope - a process that planetary geologists call groundwater sapping - it weakens the ground above it, causing it to collapse. Over time, this process may lead to the formation of steep-sided U-shaped valleys. Groundwater sapping is believed to be responsible for erosion seen in many of the valley networks on the Red Planet. [Image] Amenthes Planum in context Another eye-catching feature is the relatively deep 35 km-wide crater seen in the left-hand portion of the colour, topographic and 3D images. Spectacular landslides along the crater's walls can be seen and are particularly evident along the broken southern (left) rim. This crater sits on top of at least three older craters, the largest of which is 100 km wide and dominates the whole top left half of the 2D and 3D anaglyph images. The western rim of this crater continues beyond the image frame, and can be more easily distinguished in the context image. [Image] Amenthes Planum topography The floor of this 100 km-wide crater is chaotic, with flat-topped geological features called mesas, and their smaller siblings, buttes, littering the floor. These are probably the result of the removal of subsurface water ice leading to the collapse of weaker material around them, leaving these more resistant high-sided features behind. On Earth, the desert regions in Utah are home to many examples of these types of formation. [Image] Trough feeding Amenthes Planum Toward the north (right) side of the 2D images, several smaller craters display very smooth and flat floors, from infilling by sediments. The darker regions to the far north and south shown most clearly in the first colour image are covered in wind-transported basaltic sands. The smooth low-lying region to the far right and shown in the second perspective image is a small trough that feeds into the broader lava field of Amenthes Planum. The trough has likely been modified by the outflow of material from the ancient lake that may have once existed in Palos crater, the rim of which can only just be seen at the bottom of the colour, topographic and 3D images. This smooth, channel-like feature brushes against the rim of a 30 km-wide crater, and both have been covered with dark wind-blown materials. [Image] Amenthes Planum in 3D With these recent images, Mars Express continues to show the similarities between regions on Mars with those on our home planet. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Book of Australia/Wolf Creek Crater
I just finished a rather enjoyable old book by Arthur W. Upfield, The Will Of The Tribe, that has as a central feature Wolf Creek Crater, also referred to as Lucifer's Couch. It is a book of fiction, with a Copyright of 1962. It provides much laughter and possibly some insight into the aborigines and white ranchers of the time, around the area of Hall's Creek and the Wolf Creek Crater. If you read it, you will find that Mister Lamb provides much of the merriment. Of course, a body is found in the crater, with the back of the head bashed in. This is a Mystery book, after all. Loads of fun.

Re: [meteorite-list] Russian Meteor event?
Pieces on the ground? http://abclocal.go.com/ktrk/story?section=news/national_worldid=8993349 The ministry said some fragments fell near the town of Satka, about 200 kilometers (120 miles) from the regional capital city of Chelyabinsk.
