Production
Most carbonate or calcareous oozes are produced by the two different groups of organisms. The major constituents of nanofossil or coccolith ooze are tiny (less than 10 microns) calcareous plates produced by phytoplankton of the marine algal group, the Coccolithophoridae or by an extinct group called discoasters. Foraminiferal ooze is dominated by the tests (shells) of planktic protists belonging to the Foraminiferida. Most foraminiferal tests are sand-sized (>61 mm in diameter), so many foraminiferal oozes are bimodal in particle-size distribution, because they are made up of sand-sized foraminiferal tests and mud-sized coccolith plates.
Discoasters, coccoliths and foraminiferal tests are all made of the mineral calcite. Pteropod ooze is produced by the accumulation of shells of pteropods and heteropods, which are small planktic mollusks. As these shells are composed of the mineral aragonite, pteropod oozes are more easily dissolved, so are restricted to relatively shallow depths (less than 3,000 m) in tropical areas.
Carbonate oozes are the most widespread shell deposits on earth. Nearly half the pelagic sediment in the world's oceans is carbonate ooze . Furthermore, foraminifera and coccolithophorids have been major producers of pelagic sediment for the past 200 million years. As a result, these are arguably among the most important and scientifically useful organisms on Earth. Because their larger size makes them easier to identify and work with, this is particularly true for the foraminifera. Their fossils provide the single most important record of Earth history over the past 200 million years. That history is recorded not only by the evolution of species and higher taxa through that time, but is also preserved in the chemistry of the fossils themselves. The field of Paleoceanography owns much of its existence to biostratigraphy, isotope stratigraphy and paleoenvironmental analyses that utilize fossil foraminifera.

Again it is clear that the ocean bottoms are covered by biogenic ooze that accumulates at between 0.1- 2 mm per year, as planktonic creatures die and sink to the bottom. The maximum thickness for these biogenic sediments is about 1000 m, which means at the sedimentation rate of between 0.1 and 2 mm per year it would take between 500000 and 10 million years to accumulate the sediments seen in the ocean depths today.

Also keep in mind there are no terrigenous sediments in the deep oceans, which means the magical mystical biblical flood of creationist fundamentalists could never have happened, if it had happen, it is in these deep oceans that the sediments would have been deposited. Along with the evidence of manganese nodules and carbonate oozes there is absolutely no room for Noah’s flood, it is just another fairytale to tell your children, which they then let go of as they become adults, unless they have been indoctrinated, in which case they may believe it for a lifetime, but this also leads to the so called faithful being lead like sheep.
You have seen the evidence; creationism is the visible bull excrement of fundamentalist Christians.
