Za rudami z Čech až na konec světa

In Quest of Ores from Bohemia to the End of the World is the name of a new book by Petr Láznička, a leading Czech-Canadian-Australian geologist, published in Czech this year. Professor Petr Láznička (Peter Laznicka) is a globally renowned expert in the field of ore deposits and metallogenesis. Similar publications on the world's ore deposits in Czech are rare. We can state that the work of Professor Petr Láznička is in a way exceptional. During his 65-year career, he became a recognized authority in the fields of deposit geology and metallogenesis. Unfortunately, he has become more recognized abroad than in the Czech Republic. This book is the first comprehensive publication in Czech about Láznička’s life and work. At the same time, it is also an expression of honours to his merits in the scientific and economic knowledge of ore deposits and his approach to this complex issue.Ostrav

Sesuvná území v Malé Úpě v Krkonoších =Landslide areas at Malá Úpa in Krkonoše (Giant) Mts

Landslides are rare phenomena in Krkonoše Mts. Two best known landslide areas are at Dolní Malá Úpa in the valley of brook Kraví potok along the road connecting Spálený Mlýn and church at Dolní Malá Úpa (see Fig.1).Landslidemovements have been known and described here at least since 1968. At the locality near Javor Hotel landslides are of sheet and flow types. The main reason of last slide movement are changes in slope stability due to buildingactivityat Javor HotelLand and intensive rains. At the locality near church at Dolní Malá Úpa main landslide movement is linked with melting of snow in spring time and following erosion of unnamed brook. The main danger of renewinglandslidesactivities lies in their root areas. The most important thing is to preventleaking of water into old and newly generated fissures. It would be useful to consider the other potential slides areas in Krkonoše Mountains inorder toreduce further slide damages caused by these phenomena253
