| diatomite |
Diatomite or diatomaceous earth is a sediment greatly enriched in biogenic silica in the form of siliceous skeleta of diatoms, a diverse array of microscopic, single-cell algae. These frustules are sufficiently durable to retain much of their structure through long periods of geologic time and through thermal processing. Diatomite products have an inherently intricate and highly porous structure composed primarily of silica.
