48. Conger (1942) hypothesized that the requirements for dia-tomaceous accumulation are to have (1) conditions favour-able for diatom growth, and (2) a reduced accumulation of other sedimentary constituents that would dilute the concen-tration of the siliceous tests of diatoms. Diatom growth is dependent on many environmental factors, such as

Diatomaceous earth. Diatomaceous earth or diatomite is a light-colored sedimentary rock composed chiefly of siliceous shells (frustules) of diatoms. Diatomaceous earth is a soft and friable rock. It leaves hands dusty if touched and has a fragile feel as if it has a delicate and light-weight internal structure. This feeling is not misleading.

La diatomite, nota anche come terra di diatomee, è una roccia sedimentaria silicea, morbida e presente in natura che si sbriciola facilmente in una polvere fine da bianca a biancastra. È composto dai resti microscopici delle diatomee, alghe unicellulari con scheletri di silice. Questi scheletri si accumulano nel tempo, formando depositi di diatomite.
