Views of the main lithofacies. (a) General view of the OMO 79 deposits (occupation phases 1 and 2), T: volcanic tuff, CL: channel lag, LA: lateral accretion unit (point bar), LV: heterolithic levee/upper point bar package, FF: floodplain fines. (b) Channel lag composed of CaCO3 concretions, quartz gravel, rip-up clasts, and an in situ quartz artifact in secondary context (occurrence A127). (c) Upper point bar ripple cross-laminated sands (Sr) and heterolithic sediment package (H). (d) Clayey silt floodplain deposit with CaCO3 concretions.
