Quaternary evolution of the Pego coastal lagoon (southern Valencia, Spain)

摘要: Abstract The ancient coastal lagoon of Pego is located on the Spain Mediterranean coast. Although filling this was started by natural causes, anthropogenic action has transformed it considerably. Two coreholes were studied to recognize dynamics coast line during Quarernry. Different units detected means sedimentological and mineralogical approaches analysis foraminifera pollen found in deposits. following evolutionary stages have been recognized sedimentary record. two transgressive events (which are associated with some contemporaneous event Emiliani's stage 5), which separated environments. Afterwards, a regressive allowed maximal continental progradation, gave way establishement new lagoonal environment. These conditions continued sufficiently long allow considerable development vegetation, culminated formation peat-bog dated at 7790 8300 yr B.P. A marine transgression, commencing previous phase, until Flandrian transgression. highest beach deposit reached its maximum level about 500 modern fixed barrier took place around date, would emplacement filled lagoon.
