Discriminant analysis as a tool for the distinction of quaternary sediments in the region of Đurđevac

Discriminant analysis of Quaternary sediments in the region of Đurđevac was performed in order to determine the optimum criteria for distinguishing between previously established groups of deposits. Geological properties utilized in the procedure of discrimination are represented by the results of modal analysis. Among the seven groups related to the Quaternary sediments of the Drava river depression, only three proved to be distinctive; Pleistocene alluvial deposits (Q1), Pleistocene loess (lQ1), and Holocene deluvium (dQ2), while others proved to be modally uniform. The close relationship between characteristic minerals and individual genetic groups (Quaternary facies) proved to be useful in labelling the most prominant discriminant functions, thus equipping them with particular sedimentological meaning. Three of the six functions indicated the provenance of the source material, as well as conditions of transport and sedimentation within the Quaternary sedimentary cycle of the studied part of the Drava river depression in the Pannonian basin.
