Calcareous ooze is the general term for layers of muddy, calcium carbonate (CaCO 3) bearing soft rock sediment on the seafloor.Of all the distinct types of veneers covering the Earth 's crust â be it soil, sediment, snow, or ice â none are more widespread than red-clay and calcareous ooze.ue to a complex carbonate chemistry, calcareous ooze begins to dissolve below the calcium carbonate lysocline in the water column. Below the calcium carbonate compensation depth (CCD) calcareous ooze is completely dissolved.
