WebThe basement of the ocean basins is mostly made of black, volcanic rock called basalt. Mid-oceanic ridge volcanoes produce basalt. The centers of the continents are composed mainly of coarse-grained, light-colored rocks like granite. The blanket of sediment that covers the floors of the abyssal plains is called pelagic ooze. WebThey are more than ten times the rates observed in the central deep sea, underlying the main cyclonic gyres where biogenic sedimentation with coccolithic oozes and high organic carbon prevails (Fig. 1).IOC Workshop Report No. 145 page 15 The rate of sediment accumulation calculated on the deep sea floor is twice to six times higher than those …
