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).

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).
