Evidence of late quaternary sealevel stillstands on the upper brazilian continental margin: a synthesis

Abstract

Notable regional evidence of Holocene stillstands of sea level was gathered along the upper Brazilian continental margin, based on sedimentological, environmental and morphological data. Six persistent levels were detected approximately following the present 130, 110, 90, 75, 60 and 40 m isobaths. Radiocarbon dates and comparison with the MILLIMAN and EMERY (1968) eustatic curve assigned ages ranging from the late Wisconsin glacial maximum at 15,000 years B. P. for the deepest level to 9,000 years B. P. for the shallowest level.
