Figure 2.19: Conglomerate bed observed at CRBSGRF section with pencil shown for scale. Clasts are well rounded and comprised of iron-rich clasts (red and orange) and white lithified mud clasts. Figure 2.20: Very coarse grained quartz rich sand bed at Sleeping Giant Ridge. Orange-red hematite cement is only a surface feature- fresh faces do not show this cement. Mechanical pencil point for scale. 87
Figure 2.21: Parallel laminated silt and mud overlying wavy beds of silt and mud at Sleeping Giant Ridge. Pencil for scale. Figure 2.22: Parallel laminated silt and mud overlain by a coarser grained sand bed that is loading into the underlying finer grained bed at Sleeping Giant Ridge. Flame structures have developed. Pencil for scale. 88
