Figure F42 (continued). D. Formation factor vs. MAD porosity. Best-fit Archie's parameters were determined separately for sands (open circles) and clays (solid circles). Sediment lithology was identified based on visual observations made while taking MAD samples. Archie's parameters are m = 1.40 and a = 1.53 for clays and m = 2.35 and a = 0.523 for sands.
