Holocene palaeosalinity in a Maya wetland, Belize, inferred from the microfaunal assemblage

Abstract

A 5.4 m sequence of peat and marl overlying a basal clay in a northern Belize wetland was studied to assess salinity changes over the past 7000 yr. The distribution of ostracods, gastropods, and foraminifers revealed initially freshwater conditions in a terrestrial wetland, changing to at least mesohaline conditions by about 5600 yr B.P.. Freshwater input likely resulted from massive deforestation by the Maya that began by 4400 yr B.P.. Subsidence of the mangrove peat likely permitted the formation of a lagoon. A peat has filled the lagoon since at least 500 yr B.P.
