Re: [meteorite-list] New Martian meteorite
Hi Darren What an interesting name: Santa Catarina. There is actually already a meteorite on earth called Santa Catharina. I wonder if that will be enough of a difference to keep that name. Interestingly Santa Catharina is most likely a spelling error and should actually be spelled Santa Catarina. Since it has been spelled wrong for so long the misspelling is actually set in stone and will not be changed.

[meteorite-list] New Martian Meteorite Found in Algeria: NWA 3171
http://www.jpl.nasa.gov/snc/nwa3171.html NEW MARTIAN METEORITE FOUND IN ALGERIA: NWA 3171 Dr. Anthony Irving University of Washington August 20, 2004 Yet another Martian meteorite has been recovered from Northwest Africa, and studied by an international team, including Canadian physician and collector, Dr. David Gregory. The 506 gram basaltic shergottite was confirmed by Drs. Anthony Irving and Scott Kuehner of the University of Washington in Seattle in collaboration with Dr. Christopher Herd of the University of Alberta and Drs. Toti Larson and Fred Longstaffe of the University of Western Ontario. The rocky desert regions of Morocco, Algeria and Libya - which themselves in places closely resemble a Martian landscape - so far have produced 11 (over one-third) of the 32 known Martian meteorite specimens, with the remainder being found mostly in Antarctica and Oman. The new khaki-gray stone is partly coated by a thin black fusion crust with flow orientation (see Image 1). The sample consists of about equal amounts of prismatic, gray-brown pyroxene and sparkling, glassy maskelynite (see Image 2). As is typical of basaltic shergottites, the pyroxenes show complex compositional zoning from cores of subcalcic augite and pigeonite to more ferroan pigeonite rims (see Images 3 and 4). Plagioclase has been converted entirely to maskelynite by shock, and is compositionally inhomogeneous (An41.5 Or3.7 - An54.4 Or1.3). Accessory phases are ulvospinel, ilmenite, chlorapatite, merrillite, pyrrhotite, Na-K-Al-Si-rich glass, silica, rare baddeleyite, and rare barite and calcite (the last two probably precipitated from groundwater while the sample lay in the western Algerian desert). Grains of silica surrounded by radial cracks (see Image 5) likely represent former stishovite, and some mesostasis regions consist of quenched plagioclase needles with interstitial silica (see Image 6). The interior of the sample contains irregularly-distributed small patches of dark brown, vesicular glass (probably produced by shock induced melting), which also are visible as wart-like protrusions on parts of the exterior of the specimen (see Image 7). These glasses are being analyzed to determine whether they contain trapped Martian atmospheric gases. Thin black fractures (possibly also produced by shock) traverse the specimen, and evidently contain hydrous mineral assemblages where they intersect grains of ulvospinel. Macroscopically, this alteration appears as a rusty staining, but electron microprobe analysis has identified a complex mixture of Fe-Si-Al-Ca-Mg-Cl-K-Br(?)-bearing minerals, dominated by an iron hydroxide mineral similar to terrestrial goethite. This type of alteration is not typical of terrestrial hot desert weathering environments, and it is possible that instead it represents a hydrothermal weathering or alteration effect produced on Mars. The relative levels of oxidation or reduction (expressed as oxygen fugacity) during original crystallization of Martian shergottite magmas can be estimated from chemical analyses of iron-titanium oxide minerals and experimental laboratory calibrations. For NWA 3171, the compositions of coexisting ulvospinel and ilmenite imply an oxygen fugacity of 1.3 to 1.4 log units below the temperature-dependent quartz-fayalite-magnetite standard oxygen buffer curve, a value similar to that determined for other basaltic shergottites such as Shergotty, Zagami and Los Angeles. Replicate analyses of hand-picked pyroxene and maskelynite separates from NWA 3171 at the University of Western Ontario gave a mean oxygen isotopic composition of ?18O = 4.56 +/- 0.1, ?17O = 2.77 +/- 0.1, ?17O = 0.40 +/- 0.06 per mil, values very similar to those measured for other Martian meteorites. Based upon textures, mineral compositions and pattern of alteration, NWA 3171 is distinct from the other four African evolved basaltic shergottites (Zagami, NWA 480/1460, NWA 856 and NWA 1669). Although it is not strictly paired with these meteorites, NWA 3171 could have been launched from the same target volume as some of these other specimens by a single impact on Mars. Studies to determine the igneous formation age and cosmic ray exposure age of this new sample are underway, and the results will clarify the relationship of NWA 3171 to the other shergottites. Irrespective of the times and sites of their discovery on Earth, the number of launching impacts on Mars for the 32 presently known unpaired Martian meteorites may be as few as five or six.

[meteorite-list] New Martian Meteorite Found In Antarctica (MIL 03346)
Donald Savage Headquarters, Washington July 20, 2004 (Phone: 202/358-1727) Leslie Fink National Science Foundation, Arlington, Va. (Phone: 703/292-5395) Paul Taylor Smithsonian Institution, Washington (Phone: 202/357-2627) Jeffrey Bendix Case Western Reserve University, Cleveland (Phone: 216/368-6070) RELEASE: 04-232 NEW MARTIAN METEORITE FOUND IN ANTARCTICA While rovers and orbiting spacecraft scour Mars searching for clues to its past, researchers have uncovered another piece of the red planet in the most inhospitable place on Earth -- Antarctica. The new specimen was found by a field party from the U.S. Antarctic Search for Meteorites program (ANSMET) on Dec. 15, 2003, on an ice field in the Miller Range of the Transantarctic Mountains, roughly 750 km (466 miles) from the South Pole. This 715.2-gram (1.6-pound) black rock, officially designated MIL 03346, was one of 1358 meteorites collected by ANSMET during the 2003-2004 austral summer. Discovery of this meteorite occurred during the second full field season of a cooperative effort funded by NASA and supported by the National Science Foundation (NSF) to enhance recovery of rare meteorite types in Antarctica, in the hopes new martian samples would be found. Scientists at the Smithsonian Institution's National Museum of Natural History involved in classification of Antarctic finds said the mineralogy, texture and the oxidized nature of the rock are unmistakably martian. The new specimen is the seventh recognized member of a group of martian meteorites called the nakhlites, named after the first known specimen that fell in Nakhla, Egypt, in 1911. Like the other martian meteorites, MIL 03346 is a piece of the red planet that can be studied in detail in the laboratory, providing a critical reality check for use in interpreting the wealth of images and data being returned by the spacecraft currently exploring Mars. Following the existing protocols of the U.S. Antarctic meteorite program, scientists from around the world will be invited to request samples of the new specimen for their own detailed research. Nakhlites are significant among the known martian meteorites for several reasons. Thought to have originated within thick lava flows that crystallized on Mars approximately 1.3 billion years ago, and sent to Earth by a meteorite impact about 11 million years ago, the nakhlites are among the older known martian meteorites. As a result they bear witness to significant segments of the volcanic and environmental history of Mars. The U.S. Antarctic Meteorite program is a cooperative effort jointly supported by NSF, NASA and the Smithsonian Institution. Antarctic field work is supported by grants from NASA and NSF to Case Western Reserve University, Cleveland; initial examination and curation of recovered Antarctic meteorites is supported by NASA at the astromaterials curation facilities at Johnson Space Center in Houston; and initial characterization and long-term curation of Antarctic meteorite samples is supported by NASA and the Smithsonian Institution at the National Museum of Natural History in Washington. Details concerning initial characterization of the specimen and sample availability are available through a special edition of the Antarctic Meteorite Newsletter, to be immediately released on the Web at: http://curator.jsc.nasa.gov/curator/antmet/amn/amn.htm The edition also will be mailed to researchers worldwide. -end- __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] new martian meteorite DaG 1037
Hi all, I recently got a sample of the new DaG 1037 As you all may know, yesterday's announcement of the MetBull 88 brought up this new mars. Great thing ! It has features which you don't have in other Dag 476 etc. meteorites It is a spectacular Martian Meteorite with glassy - almost translucent appearance! This is the center piece - the missing link - of the DaG Shergottites! - It seems to origin from the exact zone where the asteroid has hit the surface of the Red Planet! Erich sells it at www.mars.li ! He states that prices will increase although it is a big meteorite. Who knows Erich knows he means (serious) what he says. best regards from Austria, Christian PS: Neuschwanstein main mass finding report was made on April 1st ;-) IMCA #2673 www.austromet.com Ing.

[meteorite-list] New Martian Meteorite Found In Morocco (NWA 1460)
http://www.jpl.nasa.gov/snc/news50.html MARTIAN METEORITE NWA 1460 FOUND IN MOROCCO Dr. Anthony Irving University of Washington February 12, 2003 NWA 1460 [Image] [Image] Image 1: Shergottite NWA Image 2: Cut face of NWA 1460 complete stone, showing 1460, showing yellow fresh fusion crust and partpigeonite grains and dark of interior. Photo © Adam maskelynite laths. Photo © and Greg Hupe. Nelson Oakes. A 70.2 gram meteorite completely coated with fusion-crust found in Morocco in December 2001 is almost certainly paired with basaltic shergottite NWA 480 (acquired in November 2000 by Bruno Fectay and Carine Bidaut). Small fragments from one end of the new stone were sent by a Moroccan dealer to Adam and Greg Hupe, who submitted it for study by Drs. Anthony Irving and Scott Kuehner at the University of Washington in Seattle. The complete stone (referred to as Black Beauty) was later purchased by Pennsylvania collector Nelson Oakes. Like the smaller 28 gram NWA 480 stone, this new stone is very fresh and is coarser grained than most other Martian meteorites. It consists mainly of large grains of compositionally zoned, low-Ca pyroxene (with orthopyroxene cores, augite mantles and pigeonite rims) and glassy, shocked plagioclase (maskelynite), with lesser amounts of two phosphate minerals (merrillite and chlorapatite), exsolved iron-titanium oxides, ilmenite, chromite, pyrrhotite, potassium-rich glass, silica and baddeleyite. A distinctive feature of both stones is the occurrence of complex intergrowths consisting of varying amounts of fayalite+hedenbergite+silica along the boundaries of pigeonite grains, which probably represent breakdown products of former pyroxferroite (an iron-rich pyroxene-like mineral first found in Apollo 11 lunar basalts). In addition, the University of Washington scientists discovered crystals of baddeleyite (zirconium dioxide) associated with the symplectites in NWA 1460. Baddeleyite was recently confirmed by Dr. Albert Jambon in NWA 480 as well, and the patterns of compositional zoning in the pyroxene grains of NWA 1460 match those found by Barrat et al. (2002) for NWA 480. The almost identical morphologies, textures and mineral compositions of both specimens suggests strongly that they are paired stones from the same fall, and the oxygen isotopic composition measured earlier for NWA 480 at the University of Paris confirms its Martian origin. The new, larger stone now will permit scientists to confirm the cosmic ray exposure age (2.4 million years) measured by Marty et al. (2001) for NWA 480, and to measure accurately the age of its igneous formation on Mars. The unusually fresh fusion crust on both stones suggests that they are part of a relatively recent fall (perhaps even within the last century) of an ancient volcanic or shallow subsurface igneous rock ejected from Mars by a large impact. There is a good possibility that other stones from the same fall also landed in the western Sahara desert, but they may be difficult to find because the exact locations of the two existing stones are known only to the nomads who provided them to Moroccan dealers.
