Periglacial structures in Grębocin near Toruń

Abstract

The author presents two levels of periglacial disturbances in Grębocin near Toruń. The lower level occurs at the top of the ribbon clays that form the base of the oldest terrace level of the Vistula River valley. The upper level is associated with marly-silty material overlying the clays and separated from them by moraine material.
