    Tectonics of the western Gulf of Oman (2018)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: Also published as: Journal of Geophysical Research 84 (1979): 3479-3489
    Description: The Oman line, running northward from the Strait of Hormuz separates a continent‐continent plate boundary to the northwest (Persian Gulf region) from an ocean‐continent plate boundary to the southeast (Gulf of Oman region). A large basement ridge detected on multichannel seismic reflection and gravity profiles to the west of the Oman line is probably a subsurface continuation of the Musandam peninsula beneath the Strait of Hormuz. Collision and underthrusting beneath Iran of the Arabian plate on which this ridge lies has caused many of the large earthquakes that have occurred in this region. Convergence between the oceanic crust of the Arabian plate beneath the Gulf of Oman and the continental Eurasian plate beneath Iran to the north is accommodated by northward dipping subduction. A deformed sediment prism which forms the offshore Makran continental margin and which extends onto land in the Iranian Makran has accumulated above the descending plate. In the western part of the Gulf of Oman, continued convergence has brought the opposing continental margin of Oman into contact with the Makran continental margin. This is an example of the initial stages of a continent‐continent type collision. A model of imbricate thrusting is proposed to explain the development of the fold ridges and basins on the Makran continental margin. Sediments from the subducting plate are buckled and incorporated into the edge of the Makran continental margin in deformed wedges and subsequently uplifted along major faults that penetrate the accretionary prism further to the north.

    Crustal structure of the Goban Spur rifted continental margin, Ne Atlantic (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 119 (1994), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: We present results that constrain the crustal structure across a typical ‘non-volcanic’ rifted continental margin, the Goban Spur in the SE Atlantic. Traveltime and amplitude modelling of wide-angle ocean-bottom seismograph profiles shows that the continental crust thins in a seaward direction to about 7 km before it breaks to allow a new oceanic spereading centre to develop. the crustal-velocity structure, the stretching factors and the density distribution inferred from gravity anomalies are consistent with bulk pure shear stretching for the development of the rifted continental margin.The seismic-velocity structure of the thinned continental crust suggests that thinning was accompanied by only limited igneous intrusion and extrusion in the upper crust. the adjacent oceanic crust is abnormally thin (5.4 km). This is explained most readily by accretion at a very slow spreading centre (approx 11 mm yr−1 full rate), although additional cooling by conductive heat loss from the parent mantle as it rose slowly beneath the stretched and thinned continental lithosphere, together with minor igneous intrusion into, and surface flows onto, the adjacent continental crust may also have reduced the oceanic igneous thickness immediately adjacent to the continent-ocean transition.

    Seismic velocity structure of oceanic crust by inversion using genetic algorithms (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 123 (1995), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: We determine the velocity structure along two expanding-spread seismic profiles, shot near the Blake Spur fracture zone in the western North Atlantic. We use the genetic algorithm as an optimization method in our inversion scheme. The genetic algorithm requires a forward modelling tool, for which we use kinematic ray tracing when traveltimes are required, and Chapman's (WKBJ seismogram) method when waveforms are needed. We optimize the seismic problem by first making a traveltime fit with velocity functions consisting of linear velocity gradients: these calculations are fast. Subsequently, we fit waveforms using B-splines for the velocity function. The splines give more consistent synthetic seismograms than linear velocity gradients because caustics caused by the model discretization do not introduce amplitude distortions, so we remain within the region of validity of asymptotic theory. We introduce a stopping criterion for genetic algorithms similar to the one used in crude Monte Carlo methods. Finally, we illustrate the whole procedure by applying the method to P- and S-wave refraction data, and compare the results of automatic inversion for the velocity-depth structure with results from trial-and-error forward modelling.

    Imaging and regional distribution of basalt flows in the Faeroe-Shetland Basin (2003)
    Oxford, UK : Blackwell Science Ltd
    Geophysical prospecting 51 (2003), S. 0 
    Details
    ISSN: 1365-2478
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences , Physics
    Notes: We demonstrate that the use of long-offset seismic data allows wide-angle reflections and diving waves to be recorded, and that these can be used in conjunction with prestack depth migrations to constrain and to image the base of the basalt flows and the underlying structure in the Faeroe-Shetland Basin. Crustal velocity models are built first by inverting the traveltimes of the recorded reflections and diving waves using ray-tracing methods. Finer details of the velocity structure can then be refined by analysis of the amplitudes and waveforms of the arrivals. We show that prestack depth migration of selected wide-angle arrivals of known origin, such as the base-basalt reflection, using the crustal velocity model, allows us to build a composite image of the structure down to the pre-rift basement. This has the advantage that the wide-angle first-arriving energy must be primary, and not from one of the many multiples or mode-converted phases that plague near-offset seismic data. This allows us to ‘tag’ these primary arrivals with confidence and then to identify the same arrivals on higher-resolution prestack migrations that include data from all offsets. Examples are drawn from the Faeroe-Shetland Basin, with a series of regional maps of the entire area showing the basalt depths and the thickness of the basalt flows and underlying sediment down to the top of the pre-rift basement. The maps show how the basalts thin to the southeast away from their presumed source west of the present Faeroe Islands, and also show the extent to which the structure of the pre-rift basement controls the considerable variations in sediment thickness between the basement and the cap formed by the overlying basalt flows.

    Notes: [Auszug] SIR - Bondi4 presents the "incontrovertible" argument that because the views of those holding different religious faiths contradict each other, then only one at most can be right.
