Cosmogenic Radionuclides in Chondrite Shower from Otway
Introduction. In the 2003/04 season, the ANSMET team recovered 83 meteorites in an elliptical area of 1.6 x 0.2 km from a blue ice field near Otway Massif in the Grosvenor Mountains (Fig. 1). The size distribution of the meteorites within this area suggests they are a well preserved strewnfield, with the largest mass (29 kg) on the East end and the smallest masses (~100 g) on the West end [1]. ...
متن کاملNoble Gases and Nitrogen in the Kle98300 Eh3 Chondrite
Introduction: The KLE98300 meteorite is an Antarctic meteorite and is classified as an EH3 chondrite [1]. In this meteorite, we found large numbers of graphite grains associated with Fe-Ni metal. Such graphite grains are considered to be products of parent body metamorphism [2, 3]. Isotopic compositions of carbon and nitrogen in graphite and in bulk meteorites give important clues to the parent...
متن کاملModeling cosmogenic radionuclides
All existing 10 Be records from Greenland and Antarctica show increasing concentrations during the Maunder Minimum period (MM), 1645–1715, when solar activity was very low and the climate was colder (little ice age). In detail, however, the 10 Be records deviate from each other. We investigate to what extent climatic changes influence the 5 10 Be measured in ice by modeling this period using th...
متن کاملOlivine Microstructures in the Miller Range 99301 (ll6) Ordinary Chondrite
Introduction: Miller Range 99301 (MIL 99301) was classified as an LL6 ordinary chondrite based on its recrystallized texture in thin section, chemical homogeneity of olivine and low-Ca pyroxene grains, and the presence of coarse (>50 μm) interstitial grains of plagioclase [1]. Determination of shock stage was problematic as various shock indicators gave contradictory information: olivine and pl...
متن کاملSubsolar Noble Gases in an Acid-resistant Residue of the Eh5 Chondrite St
Introduction: Enstatite chondrites have remarkable properties: they were formed in a reducing environment, they are putatively similar to precursor material of Earth, Venus, or Mercury, have a terrestrial oxygen isotopic composition and an uncommon noble gas signature [1-5]. Trapped noble gases in Echondrites are intermediate between solar and chondritic composition and consist of two component...
