Miocene tidal-influenced sedimentation to continental Pliocene sedimentation in the forebulge backbulge depozones of the Beni Mamore foreland Basin (northern Bolivia)
International audience Mio-Pliocene deposits of the forebulge backbulge depozones of the Beni-Mamore foreland Basin indicate tidally to fluvially dominated sedimentation. Seven facies assemblages have been recognized: FAA FAG. FAA represents a distal bottom lake assemblage, FAB and FAD are interpret...

International audience Mio-Pliocene deposits of the forebulge backbulge depozones of the Beni-Mamore foreland Basin indicate tidally to fluvially dominated sedimentation. Seven facies assemblages have been recognized: FAA FAG. FAA represents a distal bottom lake assemblage, FAB and FAD are interpreted as tidal flat deposits, FAC and FAG are interpreted as fluvial systems, FAE sediments are deposited in a subtidal/shoreface setting, and FAG represents a meandering fluvial system. The identification of stratigraphic surfaces (SU, MFS, and MRS) and the relationship among the facies assemblages permit the characterization of several systems tracts: a falling-stage systems tract (FSST) followed by a lowstand systems tract (LST), a transgressive systems tract (TST), and a highstand systems tract (HST).
