General information and occurrence
Diatomites are compact sedimentary rocks built mainly of diatom skeletons composed of the amorphous silica – opal. A closely related to them mineral raw material is siliceous earth, the loose rock. Diatomites and siliceous earth are widely used as filtration aids, absorbents for liquids, carriers for herbicides, fungicides and catalysts, thermal insulation and polishing materials. They are also used as thermal insulators and a mild abrasive. Up to the present, no typical diatomites with the SiO2 content over 80% have been found in Poland. Therefore, in spite of differences in the origin and the mineralogical composition, siliceous earth is treated as a substitute of diatomites and siliceous earth. The Siliceous earth is discussed in a separate section of this report.
Resources and output
In the Leszczawka area (Carpathian Mts.) diatomite rocks with the SiO2 content equal 72% at the average occur in the Menillite Series of the Krosno Beds. Products obtained from this mineral raw material are of a fairly limited usability. Their major uses comprise the production of light building aggregates and carriers for herbicides and fungicides. It should be noted that technological tests indicated that an appropriate processing (grinding and calcination) may improve a quality of this raw material to that of proper diatomites.
Documented anticipated economic resources of diatomite rocks are equal slightly above 10 million tonnes. Since 2000 there has been only one deposit – Jawornik – exploited in Poland. The extraction of diatomite remains at the small scale and amounted in 2023 to 1.62 thousand tonnes.
The table below shows reserves and the state of development and exploration of diatomite rocks in Poland.

Prospective resources of the diatomaceous rock in the Leszczawka area are estimated at about 10 million tonnes*. The chances for a discovery of new large diatomite deposits seem to be much higher in the case of the Menillite Series of the Krosno Beds in the areas of Godowa, Błażowa-Piątkowa-Harta-Bachórz and Dydnia-Krzywe (Podkarpackie Voivodeship). In the area of the diatomaceous rocks occurrence there is also the prognostic area Borek Nowy indicated as well as 4 prospective areas in the vicinities of: Futoma, Huta Poręby, Dobrzanka-Borownica and Leszczawka-Kuźmina. Unfortunately, the raw material in the documented deposits is of a quite law quality which causes only the minor entrepreneurs interest.
