The chemometric analysis was applied on infrared spectra of samples of three types of sedimentary rocks (claystone, clay slates and sandstones) from several localities in the Moravian-Silesian area of the Czech Republic. Determination of chlorite, muscovite, albite and quartz was performed by chemometric methods (Principal Component Analysis and Partial Least Squares Regression) in these sedimentary rocks. A separate chemometric models were developed for quantification of content of each above mentioned minerals. Results obtained by chemometric models were statistically evaluated. The infrared spectra of the sedimentary rock samples were measured by bromide pellets technique and also by diffuse reflectance technique.
