Trace element chemistry of pyrobitumen from the Tau-Tona mine in South Africa
High-grade gold and uranium mineralization in the Witwatersrand basin is intimately associated with pyrobitumen, implying that hydrocarbons may have played a role in the genesis... -

An additional ore field in the central part of the MARhas been discovered. Together with previously discovered Logachev (14°45'N) and Ashadze (12°58'N) ore fields, the new ore... -
(Table 1) Geochemistry of ODP Hole 128-798B
Because of heterogeneity, average values of sediment composition can be difficult to establish accurately in fine-grained rocks. As a result, derived values (such as biogenic... -
(Table 1) Sediment chemistry and Sulphur isotope ratios of ODP Site 127-795
Sixty sediment samples collected every 10 m from Holes 795A and 795B in the northern Japan Sea were analyzed for 27 major and trace elements using instrumental neutron... -
(Table 1) Composition of selected ash layers in ODP Site 126-792
Glass shards from 26 megascopic tephras (1-29 cm thick) were separated and analyzed for 26 elements and 87Sr/86Sr and 143Nd/144Nd isotope ratios. The isotope data allowed us to... -
Chemistry of ODP Hole 121-752B samples (Table 2)
Fourteen samples spanning a 2.5 m interval that includes the Cretaceous-Tertiary (K/T) boundary from Hole 752B near the crest of Broken Ridge in the eastern Indian Ocean, were... -
