Key Messages: (1) Thick carbonate slope-basin deposits associated with an extensive Devonian-Carboniferous carbonate platform are exposed in southern Kazakhstan. (2) Upward-thickening and -coarsening cycles of sediment-gravity flow deposits in the 200 m thick Aktobe River section are attributed to sequence-stratigraphic forcing on the platform and associated shedding of sediment onto the slope. (3) The outcropping facies architecture and stacking patterns are an excellent analog for subsurface reservoirs in the North Caspian Basin of western Kazakhstan.
