13Sedimentary facies in the distal parts of deep+marine lobes can diverge significantly from those 14 predicted by classical turbidite models, and sedimentological processes in these environments are 15 poorly understood. This gap may be bridged using outcrop studies and theoretical models. In the 16Skoorsteenberg Fm., a downstream transition from thickly+bedded turbidite sandstones to 17 argillaceous, internally layered hybrid beds is observed. The hybrid beds have a characteristic 18 stratigraphic and spatial distribution, being associated with bed successions which generally coarsen+ 19 and thicken+upwards reflecting deposition on the fringes of lobes in a dominantly progradational 20 system. Using a detailed characterisation of bed types, including grain size, grain fabric and 21 mineralogical analyses, a process+model for flow evolution is developed.

These logs were collected at 1:20 scale with more detailed logs of 85 individual beds and packages of beds collected at 1:2 scale (Figs. 2+5). Aerial photographs supported 86 field correlation in areas that were difficult to access or were covered (Fig. 2). Data collected 87 include lithology, bed thickness, and palaeocurrent measurements from ripples, flutes and other sole 88 marks. In addition, the equivalent stratigraphic intervals within cores from 7 research boreholes were 89 logged at 1:20 scale (Fig. 3).
