Abstract

Analyses comparing thermal alteration degree between main tectonic units of the Holy Cross Mts. were performed. Results indicate a distinctive heating increase of the Cambrian organic matter from the south to the north. The Lower Cambrian acritarch assemblages from the Dyminy-Klimontow Anticlinorium indicate the temperatures not exceeding 80ºC. The maximum temperature influencing the Cambrian deposits of the Kielce-Łagów Synclinorium varies from less than 80ºC to significantly exceeding 100ºC. In the Łysogóry area a significant thermal alteration of the Cambrian acritarchs suggests that the maximum temperature significantly exceeded l00ºC, locally even 300ºC.
