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. -

Article VIII.-CATALOGUE OF METEORITES IN THE COLLECTION OF THE AMERICAN MUSEUM OF NATURAL HISTORY, TO JULY i, I896. By E. 0. HOVEY. 'T'he Collection of Meteorites in the Arnerican Museum of Natural History consists of fifty-five slabs, fragments and com- plete individuals, representing twenty-six falls and finds. The foundation of the mineralogical department of the Museum was laid in I874 by the purchase of the collection of S. C. H. Bailey, in which there were a few meteorites. More were acquired with the portion of the Norman Spang Collection of Minerals which was purchased in I89I, and other meteorites have been bought by the Museum from time to time, or have been presented to it by friends. The soujrce from which each specimen came has been indicated in the following cataloguLe. This publication is made to assist. the large number of persons who have become interested in knowing the extent to which the material of various falls and finds has been distributed among collections and the present location of specimens.

Handbook of Iron Meteorites, Volume 2 (Canyon Diablo, Part 2)
Canyon Diablo 395 The primary structure is as before. However, the kamacite has been briefly reheated above 600° C and has recrystallized throughout the sample. The new grains are unequilibrated, serrated and have hardnesses of 145-210. The previous Neumann bands are still plainly visible , and so are the old subboundaries because the original precipitates delineate their locations. The schreibersite and cohenite crystals are still monocrystalline, and there are no reaction rims around them. The troilite is micromelted , usually to a somewhat larger extent than is present in I-III. Severe shear zones, 100-200 J1 wide , cross the entire specimens. They are wavy, fan out, coalesce again , and may displace taenite, plessite and minerals several millimeters. The present exterior surfaces of the slugs and wedge-shaped masses have no doubt been produced in a similar fashion by shear-rupture and have later become corroded. Figure 469. Canyon Diablo (Copenhagen no. 18463). Shock The taenite rims and lamellae are dirty-brownish, with annealed stage VI . Typical matte structure, with some co henite crystals to the right. Etched. Scale bar 2 mm. low hardnesses, 160-200, due to annealing. In crossed Nicols the taenite displays an unusual sheen from many small crystals, each 5-10 J1 across. This kind of material is believed to represent shock annealed fragments of the impacting main body. Since the fragments have not had a very long flight through the atmosphere, well developed fusion crusts and heat-affected rim zones are not expected to be present. The energy responsible for bulk reheating of the small masses to about 600° C is believed to have come from the conversion of kinetic to heat energy during the impact and fragmentation. -
