(a) Pore network volume rendering of a sample from the subhorizontal facies (800 by 800 by 500 pixels). The majority of the pores are aligned horizontally. Notice that some gastropod molds are present (see arrows). (b) 3D streamline velocity distribution within a sample from the reed facies, with preferential flow in direction, along vertical tubes, from = 0 to = 500 pixels. (c) 3D streamline velocity distribution within a sample from the waterfall facies, with preferential flow in direction from = 0 to = 500 pixels. The velocity magnitude is given in nondimensional lattice units.
