Unraveling multiple thermotectonic events accommodated by crustal-scale faults in Northern Iberia, Spain. Insights from K-Ar dating of clay gouges
Large-scale faults in the continental crust are significant features that control the evolution of sedimentary basins and intraplate mountain chains. Deciphering their evolution is a significant task because faults slip and reactivate in a variety of geological settings. In this work, clay gouges of two major orogen-scale, long-lived faults in northern Iberia, the Rio Grio and Valles-Penedes Faults, were investigated by X-ray diffraction and K-Ar isotopic analysis.
