Diatomaceous earth or celite is aorganogenic sedimentconsisting wholly or for the most part of theskeletonsfromunicellular diatomsordiatoms. Other names for thissoil typeare silica, kieselguhr, kieselguhr, mountain flour and infusoria earth  Sediments made up of diatom skeletons can form in both freshwater and seawater. Diatomaceous earth is a dewatered and compacted diatomaceous sludge located above sea level and is usually formed in lakes. Diatomaceous sludge occurs in situations where dead diatoms are not broken down and therefore accumulate in the lake or sea floor. In thedeep seaforms only diatomaceous sludge. At undersaturation onsilicate ionsPebble skeletons of diatoms already dissolve in the water column after the death of the organism. This does not happen with an excess of silicate ions, which can lead to the formation of a diatomaceous sludge. Another cause of diatomaceous sludge formation cananoxic(oxygen-free) conditions in the lower part of the water column. This is the case with lakes (or seas) with astratifiedwater column, that is to say that in the upper part of the water column there are different conditions (for example: oxygen-rich or a relatively high temperature) than in the lower part (for example: oxygen-poor (or oxygen-free) or relatively colder water). Such conditions often occur in deeper water. The ‘layers’ with different water types are oftenjump layerseparated from each other, but the transition can also take place gradually. If an organism passes the jump layer, there is often no way back and it dies. In such a situation, diatomaceous sludge can also develop..

Diatom sludge is water saturated and not compacted (compressed). Diatomaceous earth is formed from this sludge by compaction and dewatering. Through further compaction and cross-linking diatomaceous earth can form a harder rock, which is called diatomite. Because many diatomsseasonal bloomersthere is a peak in diatom sludge formation during part of the year. Because often not only diatoms settle, goessedimentationof other material outside the flowering peak. As a result, diatom sludge is often banded, for example a sediment consisting of light and dark colored layers. In such a case, each pair of light-dark layers represents a year.

seasonal or annual stratification can be used to determine the length of time over which a package of diatomaceous earth has been deposited. By counting the layer sets, the minimum number of years in which this has happened can be determined. In this way one has the minimum length of severalinterglacialscan determine. The length of itEemiancould be estimated in this way at 11,000 years, while for theHolsteinianabout 6900 annual layers were counted, so that the estimation of the length of this interglacial came to 15 to 16,000 years.
