MESOSTRUCTURAL ANALYSIS OF GLACIOTECTONIC STRUCTURES AND lIS APPLlCATION TO RECONSTRUCTION OF THE ICE SHEET ADVANCE DIRECTIONSAbstract. Study of small glaciotectonic structures, especially mesostructural analysis is an important link of the ice sheet advance direction. Geomorphology gives the synthetic view of morphostructures and sedimentology informs about sediment transport directions, whereas small glaciotectonic structure analysis lets to reconstruct a stress field of deformed sediment in a given place. Genetic interpretation of small structures not always could be certain. The outcrops deep enough for watching small and middle structures altogether is the besł place. Reconstruction of a bigger structure based on this data is possible. The next step would be preparing of detailed glaciotectonic maps. Strongly glaciotectonic involved areas which are designed to buildings ar new highways need the detailed glaciotectonic maps in the same scale as geoengineering maps (i.e. 1: 10 000 or more detailed). Engineer geologists and glaciotectonic specialists cooperation would be especially recommended for samples collecting to a resistance test (stress in situ).
