WebMar 15, 2024 · Sedimentary–tectonic dykes produced by earthquakes classified as seismites form by the injection of clastic material into (temporary) open fractures resulting from strong seismic shaking, simultaneously with fracture propagation in the host rock (e.g., Hargitai and Levi, 2014 ). 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 ... chico\u0027s watches for women
