A CHART OF THE RECENT TECTONICS OF THE ARCTIC

Summary: | In 1966, for the first time, a chart of the recent tectonics of the Arctic has been compiled, on a scale of 1 : 5,000,000, by the Institute of Arctic Geology. In the chart of the recent tectonics of the Arctic and Subarctic there are four special schematic insert-charts, as follows: (1) chart of relationships of recent and ancient geostructural regions; (2) geomorphological chart; (3) chart of types of terrestrial crust; (4) distribution chart of earthquake epicenters. The chart shows the recent structural forms of continents and ocean floors on the basis of the same unified principles of defining geostructural regions. Consequently, in the compilation of the chart, newly developed methods of showing the recent tectonic structures of the continental shelf and ocean basins have been employed for the first time.
