Fig. 1.9 Hemipelagic sediment from Sierra Leone Rise, tropical North Atlantic. Left: Fine silt-size fraction composed
of coccoliths (c), foraminiferal fragments (f) and of detrital quartz (q) and mica (m). Right: Coarse silt-sized fraction
predominately composed of foraminiferal fragments (f), some detrital quartz (q) and mica (m), scalebar 10 µm.
Fig. 1.10 Classification of deep-sea sediments according to the main constituents, e.g. clay (non-biogenic), diatoms
(siliceous biogenic), and nannofossils (calcareous biogenic); (modified from Dean et al. 1985).
