WebNeptunian dykes have been described from as varying environments as those of true clastic dykes. Moreover, complex structures coupling forceful injection from below and collapse of surface sediments within the cracks can also form, namely as the result of seismic shaking (Thorson et al., 1986). Note however that although passive fissure-fills ... WebThe use of seismic methods for the detection of dykes - underground ...

WebApr 4, 2024 · Comparing the depth of imprints in the seismic results, the imprint of the dyke is deeper than that of the terps associated with it. This would imply that the dyke might have been higher than the terps, … WebApr 1, 2024 · Depending on their degree of impermeability, these dykes present the particularity of containing a more or less permanent hydraulic head. As such, they are prone to internal erosion phenomena, such as leakage and piping, which may lead to breaching (Foster et al., 2000, Fell et al., 2003).

Pick events that involve angularities between primary reflections in order to identify unconformities and/or … WebI have identified a series of ancient dykes and dyke-induced normal in seismic reflection data, which provide 3D X-ray like images of Earth's subsurface, from the margins of a continent (NW Australia). These data present a unique and exciting opportunity to study the 3D structure of dykes and dyke-induced faults. By measuring offset of ...
WebDykes identified in the field and/or in aeromagnetic data have been indirectly recognised in co-located seismic reflection data where a localised reduction in returned seismic energy disrupts the continuity and strength …
Clastic dike environments include: • Clastic dikes associated with earthquakes – A large variety of dikes are found in the geologic record.
