MCKEEGAN Department of Earth and Space Sciences, University of California, Los Angeles, Los Angeles, California 90095–1567, USA E-mail: [email protected] It is a rare privilege to be one of the founders of an entirely new field of science, and it is especially remarkable when that new field belongs to the oldest branch of “natural philosophy.” The nature of the stars has perplexed and fascinated humanity for millennia. While the sources of their luminosity and their structures and evolution were revealed over the last century, it is thanks to the pioneering efforts of a rare and remarkable man, Ernst Zinner, as well as his colleagues and students (mostly at the University of Chicago and at Washington University in Saint Louis), that in the last two decades it has become possible to literally hold a piece of a star in one’s hand. Armed with sophisticated microscopes and mass spectrometers of various sorts, these “lithic astronomers” are able to reveal stellar processes in exquisite detail by examining the chemical, mineralogical, and especially the nuclear properties of these microscopic grains of stardust. With this special issue of Meteoritics & Planetary Science, we honor Ernst Zinner (Fig. -
Meteorites and Impacts: Research, Cataloguing and Geoethics
Seminario_10_2013_d 10/6/13 17:12 Página 75 Meteorites and impacts: research, cataloguing and geoethics / Jesús Martínez-Frías Centro de Astrobiología, CSIC-INTA, asociado al NASA Astrobiology Institute, Ctra de Ajalvir, km. 4, 28850 Torrejón de Ardoz, Madrid, Spain Abstract Meteorites are basically fragments from asteroids, moons and planets which travel trough space and crash on earth surface or other planetary body. Meteorites and their impact events are two topics of research which are scientifically linked. Spain does not have a strong scientific tradition of the study of meteorites, unlike many other European countries. This contribution provides a synthetic overview about three crucial aspects related to this subject: research, cataloging and geoethics. At present, there are more than 20,000 meteorite falls, many of them collected after 1969. The Meteoritical Bulletin comprises 39 meteoritic records for Spain. The necessity of con- sidering appropriate protocols, scientific integrity issues and a code of good practice regarding the study of the abiotic world, also including meteorites, is emphasized. Resumen Los meteoritos son, básicamente, fragmentos procedentes de los asteroides, la Luna y Marte que chocan contra la superficie de la Tierra o de otro cuerpo planetario. Su estudio está ligado científicamente a la investigación de sus eventos de impacto. España no cuenta con una fuerte tradición científica sobre estos temas, al menos con el mismo nivel de desarrollo que otros paí- ses europeos. En esta contribución se realiza una revisión sintética de tres aspectos cruciales relacionados con los meteoritos: su investigación, catalogación y geoética. Hasta el momento se han reconocido más de 20.000 caídas meteoríticas, muchas de ellos desde 1969. -

In this work was specifically investigated the fine grained matrix which is a mixture of fine-grained materials composed largely of amorphous silicate and sub-micrometre crystals forsterite and enstatite. This is thought to be the remnants of the dust and gas of the protoplanetary disk that allows us to better understand chemical and physical properties of this precursor material. -

Chapter 5: Shock Metamorphism and Impact Melting
5. Shock Metamorphism and Impact Melting ❖❖❖ Shock-metamorphic products have become one of the diagnostic tools of impact cratering studies. They have become the main criteria used to identify structures of impact origin. They have also been used to map the distribution of shock-pressures throughout an impact target. The diverse styles of shock metamorphism include fracturing of crystals, formation of microcrystalline planes of glass through crystals, conversion of crystals to high-pressure polymorphs, conversion of crystals to glass without loss of textural integrity, conversion of crystals to melts that may or may not mix with melts from other crystals. Shock-metamorphism of target lithologies at the crater was first described by Barringer (1905, 1910) and Tilghman (1905), who recognized three different products. The first altered material they identified is rock flour, which they concluded was pulverized Coconino sandstone. Barringer observed that rock flour was composed of fragmented quartz crystals that were far smaller in size than the unaffected quartz grains in normal Coconino sandstone. Most of the pulverized silica he examined passed through a 200 mesh screen, indicating grain sizes <74 µm (0.074 mm), which is far smaller than the 0.2 mm average detrital grain size in normal Coconino (Table 2.1). Fairchild (1907) and Merrill (1908) also report a dramatic comminution of Coconino, although only 50% of Fairchild’s sample of rock flour passed through a 100 mesh screen, indicating grain sizes <149 µm. Heterogeneity of the rock flour is evident in areas where sandstone clasts survive within the rock flour. The rock flour is pervasive and a major component of the debris at the crater. -
Lunar Meteorites: Impact Melt and Regolith Breccias and Large-Scale Heterogeneities of the Upper Lunar Crust
Meteoritics & Planetary Science 40, Nr 7, 989–1014 (2005) Abstract available online at http://meteoritics.org “New” lunar meteorites: Impact melt and regolith breccias and large-scale heterogeneities of the upper lunar crust Paul H. WARREN*, Finn ULFF-MØLLER, and Gregory W. KALLEMEYN Institute of Geophysics, University of California—Los Angeles, Los Angeles, California 90095–1567, USA *Corresponding author. E-mail: [email protected] (Received 06 May 2002; revision accepted 24 April 2005) Abstract–We have analyzed nine highland lunar meteorites (lunaites) using mainly INAA. Several of these rocks are difficult to classify. Dhofar 081 is basically a fragmental breccia, but much of its groundmass features a glassy-fluidized texture that is indicative of localized shock melting. Also, much of the matrix glass is swirly-brown, suggesting a possible regolith derivation. We interpret Dar al Gani (DaG) 400 as an extremely immature regolith breccia consisting mainly of impact-melt breccia clasts; we interpret Dhofar 026 as an unusually complex anorthositic impact-melt breccia with scattered ovoid globules that formed as clasts of mafic, subophitic impact melt. The presence of mafic crystalline globules in a lunar material, even one so clearly impact-heated, suggests that it may have originated as a regolith. Our new data and a synthesis of literature data suggest a contrast in Al2O3- incompatible element systematics between impact melts from the central nearside highlands, where Apollo sampling occurred, and those from the general highland surface of the Moon. Impact melts from the general highland surface tend to have systematically lower incompatible element concentration at any given Al2O3 concentration than those from Apollo 16.
