Dominios y facies deposicionales estuarinos de la desembocadura del Río Tinto (Huelva, España)

Abstract

Two estuarìne domains were distinguished in the inner mesbtidai estuary of the tinto River (S. W. Spain): central and fluvial domains; the former being subdivided into lower and upper domains. Coring and vi braco ring ofthe Ho focene sediment allowed the distinction of six depositional facies within these domains: (1) estuarìne channel, (2) tidal channel, (3) channel margin, (4) marsh, (5) fluvial flood plain and (6) fluvial bar. These facies are sequentially arranged from subtidal Into supratidal zones which meaning is the result of the infilling process of the estuary as a consequence of: (1) the stabilized sea level about 6000years BP, and (2) the great rates óf sediment accumulation
