The paper presents the results of preliminary studies on applicability of raw Krak6wiec clays to pFoduction of keramzite. The studies covered sam-ples taken from the area of southern and eastern margins of the Holy Cross Mts and the northern periphery of the Carpathian Foredeep. Most of the laboratory analyses gave positive results; the im-provements in technology gave better and better effects. It is concluded that the studies on possibi-lities of utilization of the Krakowiec clays in large--scale production of modern materials for building industry should be started.
