Deposits of fossil diatoms are called diatomite or tripolite. These deposits are composed primarily of silica and are formed from the accumulation of diatom shells over geological time. Diatomite is often used in various applications, including filtration, insulation, and as a natural pesticide. Its unique properties make it valuable in industrial and agricultural settings.
· A diatoms silica covering is called a frustule · Fossil evidence suggests that diatoms originated during, or before, the early Jurassic Period. · Some species of diatoms can reach up to 2 millimeters in length. ill post more later
The cell wall of diatoms are very thick and remain long after the diatoms die. when the cell wall remains of many dead diatoms clump together, they form a crumbly, abrasive substance called diatomaceous earth or diatomite.============================================The rock type called Chalk is also made of diatom skeletons.

Diatoms are found in various aquatic environments, such as oceans, lakes, rivers, and wetlands. They can also be found in soil, ice, and even on damp surfaces like rocks and tree bark. Diatoms are key players in aquatic ecosystems and are important primary producers.

A known deposit of fuels is called a fossil fuel reserve. These reserves are deposits of coal, oil, or natural gas that can be extracted for energy production.
