Figure F20. Formation MicroScanner (FMS) composite images. A. 2.5 m section of FMS showing examples of sinusoidal features (dashed lines) in the formation at ~425.75 and ~ 426.80 WSF. 1 = dipping north, 2 = dipping northeast. B. 2.5 m section of FMS highlighting the layered nature of the formation (bar summary to the right of image). Arrows = locations of very conductive small rounded and elongate structures that probably relate to bioturbation and associated iron mineralization (e.g., pyrite). C. 2.5 m section of FMS illustrating how braided "flaser" bands of more compressed material are represented by highly resistive bands in the image. Arrows = strongly resistive layers indicating the presence of "wispy" structures, as observed in Hole 807A core.
