Alphabetical text entries for non-Antarctic meteorites Aguada de Varas 001 (AdV 001) 24°52’S, 69°16’W Antofagasta, Chile Find: 2007 May 13 Classification: Ordinary chondrite (L5) History: The meteorite was recovered by Michael Warner while looking for fossils and meteorites in the Atacama Desert. A second trip to this location did not uncover additional meteorites. Physical characteristics: Physical Characteristics: One complete 630 g stone measuring approx. 5 × 8 × 5 cm with broken surfaces. The exterior is brownish in color with patchy, weathered brown fusion crust. Cut interior is black with a few chondrules outlined with opaques. It exhibits a sheen from numerous iron oxide veins. Petrography: (D. Hill, UAz) The meteorite is extremely weathered and is cross cut with numerous parallel iron oxide veins. The stone has a density of 3.4 g/cm3 (M. Warner). Chondrules up to 2 mm in diameter are set in a recrystallized groundmass. Most chondrules are porphyritic, especially the largest ones. Smaller barred olivine, radiating pyroxene and granulitic chondrules with diameters from 0.5-1 mm are present. Regions between these chondrules exhibit intrergrown boundaries while still preserving the relict textures of the fragments. Sulfides occur as discontinuous irregular rims up to 100 μm wide on chondrules, individual 100-μm wide irregular grains, and as lacy inclusions up to 1 cm long. Geochemistry: Mineral Compositions and geochemistry: Olivine, Fa23.8±0.5 (N=82); low-Ca pyroxene, Fs20.1±0.7Wo1.40±1.14 (N=36); Plagioclase Or1.3Ab55.1An43.6 (N=6). Although physical appearance suggests type 6, well-defined chondrule boundaries seen in microprobe BSE and olivine and low-Ca pyroxene histograms indicate type 5. Classification: D. Hill, UAz; M. Warner. Ordinary chondrite (L5, W3) Specimens: 594 g, M. Warner; 35.6 g type specimen, UAz. Al Haggounia 003 27.299°N, 12.141°W Western Sahara Find: 2013 May Classification: HED achondrite (Eucrite, unbrecciated) History: Found on May 15, 2013, by Mr. M. Smara in the Chwichiya region and subsequently purchased by John Higgins. Physical characteristics: All of the stones have pitted irregular surfaces and are light gray to dark gray to pale brown in overall color. Several stones have remnants of dark fusion crust. Most of the stones have partial coatings of greenish to whitish lichens. Petrography: (A. Irving, UWS) Unbrecciated with subophitic texture and some cross-cutting microfault zones. Minerals are exsolved pigeonite, calcic plagioclase, silica polymorph, ilmenite, troilite and minor stained metal. Geochemistry: (P. Carpenter, WUSL) Orthopyroxene host (Fs60.4-60.7Wo3.2-2.6, FeO/MnO = 31- 32, N = 2), clinopyroxene exsolution lamellae (Fs25.9-26.0Wo44.3-44.4, FeO/MnO = 30-32, N =2), plagioclase (An88.6-89.0Or0.5-0.4, N = 2). Classification: Eucrite (unbrecciated). Specimens: 24 g including one polished thin section at UWB; remaining material with Mr. J. Higgins. Annama 68.77491°N, 30.78726°E Murmanskaya oblast’, Russia Confirmed fall: 2014 Apr 19 Classification: Ordinary chondrite (H5) History: A bright fireball appeared in the night sky over the Kola Peninsula, close to the Finnish border, on April 19, 2014. It was instrumentally recorded in Finland from the Kuusamo, Mikkeli and Muhos observing sites belonging to the Finnish Fireball Working Group. Additionally, a publicly available video made by Alexandr Nesterov in Snezhnogorsk, Russia, from the opposite side of the fireball track, was carefully calibrated and taken into account in trajectory reconstruction. The fireball was very bright and was witnessed by many eye-witnesses in Russia, Finland, and Norway. The trajectory reconstruction, dark flight simulations and pre-impact orbit determination were done by Esko Lyytinen, Jarmo Moilanen, Steinar Midtskogen, Maria Gritsevich, Valery Lupovka, and Vasily Dmitriev. The initial mass of meteoroid was estimated to be about 500 kg. Based on the analysis of fireball observations it was predicted that part of the meteoroid survived atmospheric entry and reached the ground. Therefore, a meteorite recovery expedition was organized to search the calculated landing area. The international expedition participants were Alexei Ischenko, Tomas Kohout, Nikolai Kruglikov, and Grigory Yakovlev, logistically supported by Maria Gritsevich and Viktor Grokhovsky. The 5-day expedition took place at the end of May following snow melt and preceding vegetation growth. On May 29, 2014, a first 120.4 g meteorite fragment was found by Nikolai Kruglikov on a local forest road within the predicted impact area. A second 47.5 g meteorite fragment was found by Alexei Ischenko nearby on the following day. The name Annama is after a nearby river which is the closest landmark to the find location. Two subsequent expeditions did not lead to recovery of more meteorites. Physical characteristics: The 120.4 g meteorite is ~70% covered with black fusion crust, with apparent stream lines on one side. The fresh surface is bright with abundant thin dark impact melt veins. The 47.5 g meteorite is fully covered with dark fusion crust. Bulk density of both meteorites (measured with modified Archimedean method using glass beads) is 3.5 g/cm3, grain density of both meteorites (measured with gas pycnometry) is 3.8 g/cm3. Resulting porosity is 5- 8% (values measured by T. Kohout and M. Gritsevich, UHelsinki). Bulk density of the second meteorite (measured with Archimedean method using ethanol) is 3.6 g/cm3 (values measured by G. Yakovlev at UrFU). Magnetic susceptibility of both meteorites is log χ = 5.4 (χ in 10-9 m3/kg, measured by T. Kohout and G. Yakovlev). Petrography: Classification (J. Haloda, P. Halodova, CzGS) Thin sections show a recrystallized fine-grained granular texture. Chondrule shapes are readily delineated. Irregular fractures in olivine and undulatory extinction of olivine and plagioclase indicate a shock stage of S2. Thin veins of impact melt are also present. Geochemistry: EPMA results (J. Haloda, P. Halodova, CzGS ), Olivine Fa18.6±0.3 (N=60) and low-Ca pyroxene Fs16.6±0.2 and Wo1.26±0.26 (N=65). Also present are diopside (Fs6Wo46), plagioclase (Ab80An14Or6), chromite, chlorapatite, merrillite, troilite, kamacite, taenite and tetrataenite. Classification (J. Haloda, P. Halodova, CzGS), Ordinary chondrite, H5, S2, W0. Specimens: 120.4 g main meteorite was divided into a 98.4 g type specimen (UrFU), 6.2 g cut- off (Vernad), 2 thin sections (Vernad and LTKM) and several smaller (below 1 g) fragments (UHelsinki). Second 47.5 g meteorite was divided into 40.0 g and 6.6 g fragments, both located in UHelsinki. Apizaco 19.42°N, 98.13°W Tlaxcala, Mexico Find: 1961 Classification: Iron meteorite (IIIAB) History: The meteorite was found by Louis Giraud in about 1961 at the edge of a maize field in the Tlaxcala

  • 50 Years of Petrology
    spe500-01 1st pgs page 1 The Geological Society of America 18888 201320 Special Paper 500 2013 CELEBRATING ADVANCES IN GEOSCIENCE Plates, planets, and phase changes: 50 years of petrology David Walker* Department of Earth and Environmental Sciences, Lamont-Doherty Earth Observatory, Columbia University, Palisades, New York 10964, USA ABSTRACT Three advances of the previous half-century fundamentally altered petrology, along with the rest of the Earth sciences. Planetary exploration, plate tectonics, and a plethora of new tools all changed the way we understand, and the way we explore, our natural world. And yet the same large questions in petrology remain the same large questions. We now have more information and understanding, but we still wish to know the following. How do we account for the variety of rock types that are found? What does the variety and distribution of these materials in time and space tell us? Have there been secular changes to these patterns, and are there future implications? This review examines these bigger questions in the context of our new understand- ings and suggests the extent to which these questions have been answered. We now do know how the early evolution of planets can proceed from examples other than Earth, how the broad rock cycle of the present plate tectonic regime of Earth works, how the lithosphere atmosphere hydrosphere and biosphere have some connections to each other, and how our resources depend on all these things. We have learned that small planets, whose early histories have not been erased, go through a wholesale igneous processing essentially coeval with their formation.

Early days were spent using LEGO robots to automate a rotating microscope stage thanks to the efforts of our colleague Peter Whalley (now deceased). This automation speeded up image capture and allowed us to take the thousands of photographs needed to make sizeable (Earth-based) virtual microscope collections. Virtual microscope methods are ideal for bringing rare and often unique samples to a wide audience so we were not surprised when 10 years ago we were approached by the UK Science and Technology Facilities Council who asked us to prepare a virtual collection of the 12 Moon rocks they loaned out to schools and universities. This would turn out to be one of many collections built using extra-terrestrial material. The major part of our extra-terrestrial work is web-based and we The authors - Mahesh Anand (left) and Andy Tindle (middle) with colleague have build collections of Europlanet meteorites, UK and Irish Peter Whalley (right).

For the LVP data, we calculated pressures from the calibration by Leinenweber et al. [1]. For the LHDAC data, we conducted in situ determination of pressure at high temperature using the Pt scale by Dorogokupets and Dewaele [2] at synchrotron. The measured temperatures of the triple point are in good agreement between LVP and LHDAC at 1990–2000 K. However, the pressure for the triple point determined from the LVP is 3.9±0.6 GPa lower than that from the LHDAC dataset. The triple point determined through these experiments will provide an important reference point in the pressure-temperature space for future high-pressure experiments and allow mineral physicists to compare the pressure–temperature conditions measured in these two different experimental methods. Keywords: triple point; bridgmanite; akimotoite; majorite; large-volume press; laser-heated diamond anvil cell 1.

E-mail: [email protected] (Received 24 May 2007; revision accepted 19 March 2008) Abstract–We report here the petrography, mineralogy, and geochemistry of lunar meteorite Sayh al Uhaymir 300 (SaU 300). SaU 300 is dominated by a fine-grained crystalline matrix surrounding mineral fragments (plagioclase, pyroxene, olivine, and ilmenite) and lithic clasts (mainly feldspathic to noritic). Mare basalt and KREEPy rocks are absent. Glass melt veins and impact melts are present, indicating that the rock has been subjected to a second impact event. FeNi metal and troilite grains were observed in the matrix. Major element concentrations of SaU 300 (Al2O3 21.6 wt% and FeO 8.16 wt%) are very similar to those of two basalt-bearing feldspathic regolith breccias: Calcalong Creek and Yamato (Y-) 983885. However, the rare earth element (REE) abundances and pattern of SaU 300 resemble the patterns of feldspathic highlands meteorites (e.g., Queen Alexandra Range (QUE) 93069 and Dar al Gani (DaG) 400), and the average lunar highlands crust.
