    Siderophile-enriched sediments from the Cretaceous–Tertiary boundary

    Siderophilic element concentrations are high in sediments from the Cretaceous–Tertiary boundary. An extraterrestrial source is indicated. Concentrations are too high to be understood in terms of the impact of ...

    High noble metal concentrations in a late Pliocene sediment

    A 2.3-Myr-old layer in a sediment from the Antarctic Ocean contains Ir and Au at levels comparable with those at the Cretaceous–Tertiary boundary. A sizable fraction of the noble metals is contained in vesicul...

    Field evidence for active normal faulting in Tibet

    Crustal thickening does not now occur in southern Tibet. Field observations made during the Chinese–French expedition of 1980 support an earlier hypothesis based on a combined analysis of satellite images and ...

    Structure and bonding in alkali-metal-doped C60

    IT has been shown recently that MxC60 (M = alkali metal) is metallic at 300 K for some M and x (ref. 1) and superconducts below 18 K for M = potassium2. These observations give further impetus to studies of the m...
