  abstract = {{S}edimentological and paleontological studies, including foraminifera, ostracodes, gastropods, and trace fossils, were carried {O}ut on {N}eogene sedimentary successions and offshore boreholes of south-central {C}hile (similar to 33 degrees-45 degrees {S}). {S}edimentology shows the occurrence of a thin, shallow marine, basal conglomerate overlain by a succession that includes the following facies: massive sandstones, conglomerates, interbedded siltstones and sandstones showing {B}ouma cycles, parallel-laminated sandstones, synsedimentary breccias, slides, slumps, diamictites, and massive siltstones. {T}hese facies were deposited by gravity flows, with turbidity currents and sandy debris flows as the main modes of deposition. {P}aleontology indicates the occurrence of trace fossils assigned to the {Z}oophycos ichnofacies and deep-water (similar to 2000 m) benthic foraminifers, ostracodes, and gastropods. {S}edimentology and paleontology indicate that deposition took place on a slope apron during a period of rapid and major forearc subsidence. {P}lanktic foraminifers indicate ages ranging from the late {M}iocene to the early {P}liocene (zones {N}16-{N}19) for these successions. {W}e attribute this episode of major {N}eogene subsidence to an important event of subduction erosion that would have retrieved the underside of the upper continental plate and caused its thinning.},
