    Transition region of the Earth's upper mantle (1986)
    [s.l.] : Nature Publishing Group
    Nature 320 (1986), S. 321-328 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The transition region of the Earth's upper mantle, 400–650 km deep, appears to be mineralogically and chemically distinct from both the shallow mantle and lower mantle. It contains most of the basalt fraction of the Earth's ...

    Earth science: A new look at the inner core of the Earth (1983)
    [s.l.] : Nature Publishing Group
    Nature 302 (1983), S. 660-660 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE inner core is slightly smaller than the Moon but is more than three times denser. It represents less than two per cent of the mass of the Earth but nevertheless has had important effects on the Earth's magnetic field and on the thermal history of the core. The change in physical properties at ...

    Geochemistry: Chemical inhomogeneity of mantle above 670 km transition (1984)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] WHAT chemical composition the mantle has and on what scale mantle convection takes place are related questions which require data from both seismology and petrology to answer. The mantle, which represents about 68 per cent of the Earth's mass, is usually considered, especially by petrologists, to ...

    Aspherical heterogeneity of the mantle from phase velocities of mantle waves (1984)
    [s.l.] : Nature Publishing Group
    Nature 307 (1984), S. 117-121 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Long-period surface waves are used to map the lateral heterogeneity of the upper 100–600 km of the mantle. There is good correlation of velocity with surface tectonics and heat flow. Convergence regions are generally slow for Love waves and fast for Rayleigh waves. Back arc basins have slower ...

    Hotspots, polar wander, Mesozoic convection and the geoid (1982)

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The Earth's largest positive geoid height anomalies are associated with subduction zones and hotspots and bear no simple relationship to other present-day tectonic regions such as continents and ridges. When the subduction-related geoid highs are removed from the observed field the residual geoid ...

    Bulk attenuation in the Earth and viscosity of the core (1980)
    [s.l.] : Nature Publishing Group
    Nature 285 (1980), S. 204-207 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Recent studies indicate that bulk absorption is required somewhere in the Earth to explain the damping of the radial modes of free oscillation. This excess absorption, if attributed to bulk viscosity in the core, requires a value of ∼500 P. This is theoretically reasonable and may be due to ...

    Notes: [Auszug] THIS volume is a collection of 17 review papers written to honour the two outstanding geophysicists who were responsible for the development of earth sciences at the Australian National University in Canberra. Under the direction of John C. Jaeger and Anton Hales, the ANU has become a world centre ...

    Notes: [Auszug] Explanation of the Moon's composition in a model for the condensation of the planets from a cloud of solar composition suggests that the Moon accreted at higher temperatures and lower pressures than the terrestrial planets. This may be explained if the lunar orbit initially had a high ...

    Notes: [Auszug] Assuming the Earth accreted uniformly with respect to composition 4.5 x 104 yr ago, we have concluded that core formation could have been simultaneous with the accretion process3. The initial temperatures necessary to lead to core formation, together with the temperature rise on core formation, ...

    Notes: [Auszug] THE study of the Earth's core might seem to be as academic as the study of a black hole or a pulsar. If it were not for the core, however, compasses would not work, we wouldn't know about plate tectonics and we probably wouldn't even have evolved to worry about such things. The core is a sloshing ...
