CRUSTAL STRUCTURE AND THE MECHANICAL-PROPERTIES OF EXTENDED CONTINENTAL LITHOSPHERE IN THE VALENCIA TROUGH (WESTERN MEDITERRANEAN)

Journal article

Seismic refraction and reflection, gravity and well data have been used to constrain the structure and evolution of the Valencia trough: a young extensional basin in the western Mediterranean. The best overall fit between the predicted and seismically constrained crustal structure in the trough is for a model in which the extended continental crust and lithosphere has acquired little or no strength following rifting. There are discrepancies between the observed and predicted Moho depths beneath the flanks of the Valencia trough, but they are attributed to either the removal of crustal material during or following rifting or to orogenic loading of previously extended continental crust. The largest discrepancy (up to 10 km) correlates with the Ebro delta which has prograded into the trough by more than 60 km since the Pliocene. -from Authors
