【 摘 要 】

The territory of Northern Moravia and Silesia is outstanding from the geological point of view. The abundance of different mineral resources has largely contributed to the intense development of the territory, particularly in the 19th century. Mineral resources were discovered already in the pre-historic period, when pre-historic man found coal at the coal seam exposures in Ostrava-Landek. They also used some raw materials that had been transported there by glacial action of the last Saale glaciation. Flint fragments and other travelled material may be frequently found in many localities to date. Large pieces that are called glacial boulders have been removed and exhibited for more than a century in many towns of the region. These vestiges of glacial action represent one of the many stages the Earth has passed through its history. At present, such findings mainly have an aesthetic function. Particularly interesting specimens have been protected as national monuments. The geomorphology of Ostrava has been responsible for the findings of the largest glacial boulders within the Czech Republic. Many of the formations are fascinating specimens that enrich the list of numerous geomontane sights in the City of Ostrava.
