diatomaceous earth localities
Diatomaceous earth - Wikipedia
In Germany, diatomaceous earth was also extracted at Altenschlirf on the Vogelsberg (Upper Hesse) and at Klieken (Saxony-Anhalt). There is a layer of diatomaceous earth more than 6 meters (20 ft) thick in the nature reserve of Soos in the Czech Republic. Deposits on the isle of Skye, off the west coast of Scotland, were mined until 1960.

Diatomaceous Earth - Dicalite Management Group
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.

These fossils allow to establish relative ages of the strata in which they are found and also serve to relate the strata of different localities. Diatomaceous earth. Diatomaceous earth is known as large deposits of fossilized microalgae that are found mainly on land. The most important deposits of these lands are in Libya, Ireland and Denmark.

INSECTICIDE POTENTIAL OF DIATOMACEOUS EARTH FROM
Diatomaceous earth (DE) is a geological deposit consisting of the fossilized skeletons of numerous species of siliceous marine and fresh water one-cellular organisms, particularly diatoms and other algae. The skeletons are made of amorphous silicon dioxide. DE is probably the most effective natural inert dust used as an insecticide. DE is a low toxicity, natural insecticide.

CSMS GEOLOGY POST: July 2013
Diatomite or diatomaceous earth, is a sedimentary rock composed of the fossilized remains of diatoms, a type of algae with an opalized skeleton. Interestingly, this nondescript opal has by far the most value since the uses in industry are enormously varied—from filters to insecticides to cat litter. In this part of the country the best known beds of diatomaceous earth are from the

—The diatomaceous deposit, so often called "Bermuda" or "Bermuda tripoli," especially by foreign writers, is in reality the Miocene stratum extending for miles along the Patuxent River near the village of Nottingham, Md. The author is perfectly familiar with the location, having made large collections there. The mistake in the name is due to the fact that Prof. Bailey received material

Wellheim Formation - Wikipedia
The Wellheim Formation is a geological formation in southern Germany deposited during the Cenomanian to earliest Turonian stages of the Upper Cretaceous.. The Formation is subdivided into three member units: unnamed basal marine sandstone, the Neuburg Kieselerde Member, and an upper silicified conglomerate (Homsand facies). Geographically, this formation is located in
