AbstractUpper Cretaceous strata outcropping in the vicinity of Laguna Figueroa, southern Chile record the sedimentary processes of a deep-water, slope channel depositional setting within the Magallanes foreland basin. The strata investigated is exposed over a 6 km long by 100 m thick depositional dip-oriented outcrop, which is cross cut by numerous gullies that provide strike perspectives. Measured sections, paleoflow measurements, photomosaic interpretations, and geo-referenced stratigraphic surfaces are used to construct a 3-D digital outcrop-based model that consists of a hierarchy of channelform sedimentary bodies. Five mappable channel elements, 10-20 m thick, comprise a single 60 m thick channel complex. The succession of channel element deposits transition from laterally offset to more vertically aligned down-slope over 2 km. Similar architectural transitions are common to conduits that transect topographically complex slope systems on numerous continental margins, including petroliferous regions of west Africa and the Nile Delta.
