Summary: This paper presents the opinion of application of the pedological Scheibler method in estimation of the calcium carbonate content from highly cemented carbonate deposits. The Scheibler method belongs to volumetric analysis in which content of CaCO3 is calculated from volume of emitted carbon dioxide as a consequence of reaction of the rock sample with HCl. Investigations are realized using Scheibler apparatus taking the readings of CO2 volume from the measuring pipe. Percentage calculation of carbonate content is calculated on the base of formula "1". Marls and limestones from mid-Cretaceous section at Stare Bystre (Pieniny Klippen Belt) were exposed to the action of this method. Results of studies have been listed in Tab. 1. In order to verify the correctness of these results, thermogravimetric analysis has been made for ten selected samples. On the basis of TG and DTA curves, the content of calcite has been estimated. Calcite has suffered desintegration in temperature 850-900°C during warmig up. It was strong endothermal reaction. The results of these investigations and their comparison with results based on the Scheibler analysis have been compiled in Table 2 and Fig. 4. In this comparison concurrence of results from these methods for light (oxidized) deposits is well visible. However, the values from the Scheibler method are a little higher (6.8%) for dark-grey and black deposits. This is an effect of additional CO2 acummulation of sulphuretted hydrogen (H2S) which was created as a result of HCl reaction with sulphides. Consequently, this surplus is approximate content of sulphides in the rock. The above mentioned results give possibility to adopt Scheibler method in researches of this type of deposits. This way, time-consuming and expensive indications of CaCO3 by thermogravimetric, chemical and others methods can be successfully replace by this one.
