[802] PRINT ONLY: CHONDRITES AND THEIR COMPONENTS
Berzin S. V. Erokhin Yu. V. Khiller V. V. Ivanov K. S. Variations in the Chemical Composition of Pentlandite in Different Ordinary Chondrites [#1056] The chemical composition properties of pentlandite from different ordinary chondrites was studied.
Caporali S. Moggi-Cecchi V. Pratesi G. Franchi I. A. Greenwood R. C. Textural and Minerochemical Features of Dar al Gani 1067, a New CK Chondrite from Libya [#2016] This communication describes the chemical, petrological, and oxygen isotopic features of a newly approved carbonaceous chondrite from the Dar al Gani region (Libya).
Cortés-Comellas J. Trigo-Rodríguez J. M. Llorca J. Moyano-Cambero C. E. UV-NIR Reflectance Spectra of Ordinary Chondrites to Better Understand Space Weathering Effects in S-Class Asteroids [#2610] We compare the UV-NIR spectra of S-type asteroids with several L and H ordinary chondrites, in order to better understand space weathering effects on spectra.
Fisenko A. V. Semjonova L. F. Kinetics of C, N, Ar, and Xe Release During Combustion of the Small Metal-Sulphide Intergrows of Saratov (L4) Meteorite [#1071] It’s shown the metal-sulphide intergrows of Saratov chondrite contains Ar and Xe. They either are dissolved in pentlandite or are in its carbonaceous inclusions.
Kalinina G. V. Pavlova T. A. Alexeev V. A. Some Features of the Distribution of VH-Nuclei Tracks of Galactic Cosmic Rays in Ordinary Chondrites [#1019] The tendency of decreasing of the average rate of track formation with increasing of cosmic ray exposure ages of meteorites is found and discussed.
Kletetschka G. Nabelek L. Hruba J. Magnetic Forces on Small Bodies Can Be Characterized by Magnetic Scans [#1657] In order to move objects on the asteroid surface by magnetic force it requires in situ knowledge of minerals’ magnetic coercivity of remanence.
Lavrentjeva Z. A. Lyul A. Yu. A Comparative Study of Elemental Abundances in Magnetic Fractions from Abee EH4, Adhi Kot EH4 and Atlanta EL6, Pillistfer EL6 Enstatite Chondrites [#1061] The results of elemental abundances in magnetic fractions from Abee EH4, Adhi Kot EH4 and Atlanta EL6, Pillistfer EL6 of enstatite chondrites are reported.
Lehner S. W. Buseck P. B. Fine-Grained Aggregates in EL3 MacAlpine 88136 and EH3 Larkman Nunatuk 06252 [#2463] Fine-grained aggregates in EL3 and EH3 chondrites reflect the formation of primitive regolith. Such regolith is a possible environment for silicate sulfidation.
Lindgren P. Blamey N. J. F. Parnell J. Lee M. R. Formation and Preservation of Methane in Aqueously Altered and Shocked CM Carbonaceous Chondrites [#1133] Methane has been detected in a suite of CM carbonaceous chondrites that are serpentinised and shocked to various degrees.
Martínez-Jiménez M. Trigo-Rodríguez J. M. Brearley A. J. Llorca J. Mestres N. Aqueous Alteration in the Unequilibrated H/L Ordinary Chondrite Tieschitz [#1590] The Tieschitz H/L chondrite provides evidence that fluids in ordinary chondrites played an important role during the early stages of asteroidal metamorphism.

Rubin A. E. Breen J. P. Isa J. Tutorow S. New Kind of Chondrite: A Clast with Carbonaceous, Ordinary, and Unique Characteristics in the Northwest Africa 10214 LL3 Breccia [#1048] A 6 × 7 mm clast in an LL3 breccia has 60% matrix, 0.6% CAIs (D17O = –23‰) and PP chondrules with OC-like O-isotopes. It may be a new rather-reduced matrix-rich OC.
Rubin A. E. Reduced, Aged, and Disturbed: Al Haggounia 001, the Largest Known Enstatite Meteorite, a Fossil EL Chondrite and a Vesicular Impact-Melt Breccia [#1049] Al Haggounia 001 and pairs constitute a >3-ton vesicular impact-melt breccia that fell 23 ka ago. The composition was severely affected by shock and weathering.
Schmitz B. Sediment-Dispersed Extraterrestrial Spinel Grains Link the Histories of Earth and the Asteroid Belt [#1357] The meteorite flux over geological time is being reconstructed. Is there a correlation between asteroid showers and perturbations of climate and life on Earth?
Szurgot M. Mean Atomic Weight of L/LL and H/L Intermediate Ordinary Chondrites [#2180] Mean atomic weight of L/LL and H/L chondrites was determined and certain physical properties of H/L chondrites parent body have been predicted.
Vergara-Pinto A. Trigo-Rodríguez J. M. Reche Estrada J. Bischoff A. Ebert S. et al. Claromecó L5/6 Chondrite: A Large and Moderately Weathered Argentinian Find [#1917] Claromecó is a L5/6 ordinary chondrite found in the Argentine Pampas on 1963. We characterize here this moderately weathered (W2-3) and shocked (S3) meteorite.
