This study is a review of Hungarian research on the periglacial frozen ground phenomenon emphasising the works of Professor Pécsi. The extent and attributes of the periglacial zone and features has been discussed since Szádeczky-Kardoss identified the first periglacial relics in Hungary. Unfortunately, according to the results of international research in the last decade, there is also some uncertainty on the last European permafrost maximum. The main goal of this paper is to evaluate former national research and to provide new insights into the current state of understanding on periglacial ground features in Hungary. Former studies on wedge shaped frost features were reinterpreted and compared to international standards. Ice and frost wedge casts were detected as relict sand wedges as proxies of the DPZ or the SPZ. Although several authors depicted the southern limit of the past permafrost zone as crossing the Pannonian Basin, the certain ground frost evidences of CPZ are still missing. Based on the estimated old relative and new numerical ages, the relict sand wedges were formed in the late Pleistocene during the LGM. [ABSTRACT FROM AUTHOR] |
