Diferenciación de facies relictas y actuales en los sedimentos recientes de los fondos de la bahía de Cádiz

In subtidal littoral zones and inner continental shelf, recent sea level changes force to coexist relict sediment sdeposits, formed when sea level was lower than nowadays, with more recent sediments which are in equilibrium with hydrodynamic agents. Cadiz bay sea bottom sediments has been studied in...
