Diatomaceous earth is a naturally formed, sedimentary mineral rock. It's derived from the remains of diatoms — oceanic unicellular algae. [] Diatoms are over 30 million years old, and they're formed from the cementation of microscopic, algae-like plant remains into the earth's surface.

Answer (1 of 8): These are Diatoms. Actually these are their tiny little skeletons. They are, and were, alive in the Earth's oceans billions of years ago and helped to create the oxygen we breathe. They are very very small- 20~200 microns on average and are formed of calcium carbonates. En mass...

Diatomaceous earth, also known as diatomite and DE, is the naturally occurring fossilized remains of diatoms—single-celled aquatic algae. It is a near-pure sedimentary deposit consisting almost entirely of silica. Diatoms will grow in almost any environment that combines water and sunlight, allowing them to be found in both fresh and saltwater.
