Zarys historii górnictwa skalnego w rejonie Sitkówki (Góry Świętokrzyskie) w I połowie XX w.

Rock quarrying in the vicinity of the Sitkówka (Sitkówka-Nowiny commune, Kielce county), which started at the beginning of the 20th century, has not yet been given a historical context. The authors based on archival sources, present the history of the development of six quarrying and processing plants involved in the extraction of rock raw materials in the first half of the XXth: Sitkówka, Jaźwica Mala, Sitkowieckie Nowiny, Belkowa, Kostrzewa and Stara Trzuskawica. The principal rochi extracted in these quarries were Middle Devonian-Givetian dolomites and stromatoporo- id-coral limestones of the Kowala Formation (Lower Sitkówka Beds). They were used mainly for the production of crushed stone, grits and lime, and less frequently of technical marbles. The modern, intensive activity of numerous industrial plants causes constant transformation of the Sitkówka area thus obscuring traces of the former quarrying activity and production infrastructure. That is why documentation of the remains of this exploitation is so important.
