Diatomite (Chapter 33)
Introduction. Diatomite, a soft, porous, fine-grained, lightweight, siliceous sedimentary rock, is produced by the accumulation and compaction of diatom (Class Bacillariophyceae) remains. The cell wall of living diatoms is impregnated with silica (amorphous hydrous, or opaline (SiO 2. n H 2 O)), which preserves ornate and highly …

Diatomite: Description, Characteristics, and Other FAQs
Diatomite is a sedimentary rock that consists chiefly of the siliceous remains of diatoms. Diatoms are single-celled algae that have a hard shell of carbonaceous material (called a frustule). The frustules are the main component of diatomite, and they vary in size and shape. Diatomite has a porosity of up to 90 percent, making it an extremely ...

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.
