The continental shelf offshore the present-day Amazon River is known to have hosted a mixed carbonate-siliciclastic platform from the Late Paleocene to the Late Miocene. However, character of this platform has not been properly described and the nature and timing of the cessation of carbonate sedimentation remains controversial. In the present...

The Amazon continental shelf hosted one of the world's largest mixed carbonate-siliciclastic platforms from the late Paleocene onwards - the Amapá carbonates. The platform architecture, however, remains poorly understood and causes and timing of the cessation of carbonate deposition are still controversial. Here we present a stratigraphic...

Extra sets of 2D multi-channel seismic and chronostratigraphic data allowed us to undertake analyses of source to sink processes and triggering mechanisms of the gigantic megaslides previously documented off the NW and SE steep slope settings of the Foz do Amazonas basin. As these megaslides comprise two sets of stacked allochthonous masses...
