General information and occurrence

Veins of crystal calcite, genetically originated from the hydrothermal-ascending processes, occur within the Middle Devonian limestones and dolomites in the Kielecko-Chęciński region and within the Lower Carboniferous limestones in the area of Krzeszowice (the Paczółtowice-Czarna region). The calcite deposits of an economic importance, occurring in the form of veins, were documented in Świętokrzyskie Voivodeship.

Calcite is used in the ceramic industry as an additional compound. Nevertheless, it has been lately replaced by other high-calcium raw materials. In the past, it was used in the glass industry, as an attractive fancy stone for a sacral building (i.e. różanka zelejowska and różanka paczółtowska – Polish names) and as a compound of precious grits.

Resources and output

The anticipated economic resources of calcite, documented within 3 deposits, are estimated at 232.78 thousand tonnes as of 31.12.2022. The resources have not changed for many years. The most calcite-bearing is the Skrzelczyce deposit, where the coarse-crystalline calcite vein is of about 640 m long and about 25-42 m wide. In the Polichno-Skiby deposit there are two calcite veins about 300 m long and from 3 m to 16 m thick. Only in the Radomice I deposit calcite is occurring as the main raw material, in other deposits there were limestones for building and road industries documented, while calcite is an accompanying raw material.

In 2022, none of the calcite deposits was covered by the exploitation concession. For many years none of the calcite deposits has been exploited mainly due to the economic reasons and the environmental protection aspects.
