SUMMARY

Results of mineralogical sbudies on upper loess horizon a·t Zwierzyniec near Cracow are given. Raw samples of loesses were separatedhlto size classes and subsequently s·tudied by microscopic, X-ray, and Infrared &pectrophotometric methods. The results ob-tained were used in attempt to Identify .a'll~genic miner~. The clay minerais are represented by ruite,' montmorillonite, kaollnlte, and by minerals with mi-xed, illite-montmorillonite textures. The results

0b-tained are discussed on thel:>ackgl'Olmd of recent dis-cuSsions on the origin loesses.
