Bed variability of sediment-gravity-flow deposits is quite prevalent in deep-marine settings,
but it has not been well investigated in lacustrine settings. The depositional characteristics of
various event beds are characterized in the North Slope Belt of the Bongor Basin (Chad),
using detailed sedimentological, petrographic, geochemical as well as palynological
analysis. Four bed types including classical turbidite bed, debrite bed, hybrid event bed, and
hyperpycnite bed were distinguished based on their interpreted depositional processes …
