Estructuración sedimentaria de los cuerpos deltaicos holocenos del margen septentrional del mar de Alborán

Abstract

In three deltaic areas of northem Alboran Sea margin, the different depositional bodies that establish the sedimentary structure of the holocene progradational wedge has been determinated by high resolution seismic profile (3.5 kHz). Four seismic units have been diferenciated: FI seismic unit (a weak one with an oblicuo-progradational reflection configuration), F2 seismic unit (transparent), F3 seismic unit (a weak one with a sigmoidal-oblique reflection configuration), and F4 seismic unit (transparent). Each one is a real little scale depositional sequence in relation to allocyclical processes by high frecuency eustatic variations during the last 6.000 years
