    Cosmic-ray production of tungsten isotopes in lunar samples and meteorites and its implications for Hf-W cosmochemistry by Leya, I, Wieler, R, Halliday, A

    Published 2000
    “…Lett. 152(1997) 181-185] showed that neutron-capture reactions on tungsten isotopes can account at best for a minor part of the observed deficit of 182W in Toluca and other iron meteorites. On the other hand, in lunar samples and stony meteorites the production of 182W from 181Ta may become crucial. …”

    Correlated helium-3 and tungsten isotopes in iron meteorites: Quantitative cosmogenic corrections and planetesimal formation times by Markowski, A, Leya, I, Quitte, G, Ammon, K, Halliday, A, Wieler, R

    Published 2006
    “…This may severely limit the use of the Hf-W system for determining chronologies of metal segregation as recorded in iron meteorites. Here we present the first experimental evidence of cosmogenic effects on W isotopes in two magmatic iron meteorites, Carbo (IID) and Grant (IIIAB). …”

    In situ U–Pb dating of 4 billion-year-old carbonates in the martian meteorite Allan Hills 84001 by R. Tartèse, I. C. Lyon

    Published 2022-12-01
    “…To assess the robustness of the carbonate U–Pb chronometer in deep time, we carried out in situ U–Pb analyses in magnesite–ankerite–calcite carbonates in the martian meteorite Allan Hills (ALH) 84001. Carbonates in ALH 84001 formed at ca. 3.94 <span class="inline-formula">Ga</span>, and there is little evidence that much happened to this rock since then, making it an ideal sample to test the robustness of the U–Pb system in old carbonates. …”

    Community involvement in the development of an environmental education programme: the Tswaing meteorite crater conservation area as a case study by C.H. Swanepoel, C.P. Loubsser, E.M.J.C. Schaller

    Published 2004-12-01
    “…A case study was undertaken to determine how research insights could be implemented by involving a local community in the design and implementation of environmental education programmes in their environment. The Tswaing Meteorite Crater conservation area project was undertaken with the active participation of teachers, learners and education officers from the communities living around Tswaing, as well as subject specialists. …”
