Abstract
The extension of the brazilian coast between Salvador and Ilheus (Bahia) shows evidences of two distinct episodes of transgression in the Quaternary, deduced from the observation of sandy littoral deposits above the present mean sea level:(a)one, older, related to the event of 120.000 years B.P. (Late Pleistocene), and (b) the other, more recent, related to the end of the last great transgression (Holocene). After the deposition of the Barreiras Formation (Pliocene) under a continental and dry climate, followed period of humid climate, succeded by a new dry period, when a new detritic continental formation has been deposited. Before the maximum of the last but one transgression (120.000 years B.P,). the climate became humid again, and since that time it has not presented any appreciable variation. The Quaternary deposits have been submitted, locally, to deformations connected to sinking and tilting of blocks.
