| Summary: | PROGRESS IN CARTOGRAPHY AND IN REGIONAL RESEARCH DURING THE LAST 4 YEARS PERIOD OF ACTIVITY OF THE COMMISSION FOR GEOLOGICAL MAP OF THE WORLDSummaryThe purpose of this report is to inform Polish geologists of the world's progress in cartography and in regional research according to the results presented at the plenary session of the Commission for Geological Map of the World, held in Paris in March 1970. The present report includes also summaries of respective resolutions and gives a list of the articles handed during the session.Progress in cartography of Europe. the first part of the report comprises the state of development of the international maps of Europe, mainly metallogenic, iron ore, natural gas, tectonic, metamorphic and Quaternary maps on a scale 1:2 000 000, geologic and hydrogeologic maps on a scale 1:000 000, as well as a world's geological atlas on a scale 1:10 000 000 . .In addition to this, there are given some more important elements of the legend of these maps; and their influence upon the development of geological reconnaissance in Europe is discussed.Progress in regional geology of the world. The second part gives new results of regional research, discussed during the plenary session devoted to geologic maps.1. A. A. Thiadens (Netherlands) presented a map of the Zechstein salt plugs in the south-western part of the North Sea. These plugs run along several lines in a NS direction.2. H. R. V. Gaertner (GFR), discussing the diaphthoritic·alteration of the Central Alps, informed that after folding processes these zones had been strongly uplifted and then eroded, the amplitude of these movements amounting up to 15000 m.3. A. A. Bogdanov (UofSSR) informed that geophysical surveys had demonstrated that the basement of the West-Siberian platf.orm in the Karskoe Sea is at a depth of about 8000 m.4. A. E. Escher (Denmark - Greenland) emphasized that gneisses, wide-spread in the eastern area of Greenland, are thought to be of Caledonian origin and, according to the recent studies, are referred to ...
