Figure F5. Downhole variations of grain size, textural statistical parameters, calcium carbonate, and magnetic susceptibility from (A) Hole 1245B, (B) Hole 1247B, and (C) Hole 1248C located on the east flank of southern Hydrate Ridge. BSR = bottom-simulating reflector, IR = infrared. (D) Downhole variations in bulk (calcite, clays, quartz, and feldspars) and clay (smectite, detrital mica, chlorite, and kaolinite) mineralogy in Hole 1247B. Semiquantitative analyses show changes or gradients in mineral abundances rather than absolute values.
