Figure F5. Summary of the recovered section at Site 1148, showing lithologic units, sediment types, lightness intensity (L* parameter) and the a* parameter, coulometer carbonate and clay, biogenic carbonate, and biogenic silica estimates from smear slides. High positive values of a* correspond to high red intensity, whereas high negative values correspond to high green intensity. L* and a* values correspond to measurements from Hole 1148A.
