    Earth science The ultraslow difference (2003)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] Earth exploration still has the power to astound. Mid-ocean ridges, also called spreading centres, produce new ocean crust at different rates and are classified accordingly. Dick and colleagues (page 405 of this issue) show that ridges exhibit fascinating behaviour when the spreading rate is ...

    Seismic constraints on mantle flow and topography of the 660-km discontinuity: evidence for whole-mantle convection (1993)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] Recent seismic models of three-dimensional mantle structure and topography on the transition-zone seismic discontinuities permit the direct evaluation of the buoyancy forces that drive large-scale mantle flow. This buoyancy distribution, coupled with radial viscosity models that are consistent with ...

    Flattening of the sea-floor depth-age curve as a response to asthenospheric flow (1992)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] We start from a feeling that previous explanations for the flattening of the sea-floor depth-age curve are not entirely satisfactory. Hotspot rejuvenation models3'4 predict heat flow and seismic slowness anomalies, yet no such anomalies are observed7'9. The classic 'plate' model1 assumption of ...

    Deep Roots of the Messinian Salinity Crisis (2003)
    Nature Publishing Group
    In:  Nature, 422 . pp. 602-606.
    Details
    Publication Date: 2019-09-23
    Description: The Messinian salinity crisis—the desiccation of the Mediterranean Sea between 5.96 and 5.33 million years (Myr) ago1—was one of the most dramatic events on Earth during the Cenozoic era2. It resulted from the closure of marine gateways between the Atlantic Ocean and the Mediterranean Sea, the causes of which remain enigmatic. Here we use the age and composition of volcanic rocks to reconstruct the geodynamic evolution of the westernmost Mediterranean from the Middle Miocene epoch to the Pleistocene epoch (about 12.1–0.65 Myr ago). Our data show that a marked shift in the geochemistry of mantle-derived volcanic rocks, reflecting a change from subduction-related to intraplate-type volcanism, occurred between 6.3 and 4.8 Myr ago, largely synchronous with the Messinian salinity crisis. Using a thermomechanical model, we show that westward roll back of subducted Tethys oceanic lithosphere and associated asthenospheric upwelling provides a plausible mechanism for producing the shift in magma chemistry and the necessary uplift (approx1 km) along the African and Iberian continental margins to close the Miocene marine gateways, thereby causing the Messinian salinity crisis.

    Bending-related faulting and mantle serpentinization at the Middle America Trench (2003)
    Nature Publishing Group
    Details
    Publication Date: 2023-09-26
    Description: The dehydration of subducting oceanic crust and upper mantle has been inferred both to promote the partial melting leading to arc magmatism and to induce intraslab intermediate-depth earthquakes, at depths of 50–300 km. Yet there is still no consensus about how slab hydration occurs or where and how much chemically bound water is stored within the crust and mantle of the incoming plate. Here we document that bending-related faulting of the incoming plate at the Middle America trench creates a pervasive tectonic fabric that cuts across the crust, penetrating deep into the mantle. Faulting is active across the entire ocean trench slope, promoting hydration of the cold crust and upper mantle surrounding these deep active faults. The along-strike length and depth of penetration of these faults are also similar to the dimensions of the rupture area of intermediate-depth earthquakes.
