Geological maps from East View

Russian geological maps are noteworthy for their detail and richness. These maps are prepared according to standardized rules with their content showing pre-quaternary formations, quaternary and other deposits, the location of identified mineral resources (oil, gas, coal, ferrous and non-ferrous metals, precious and rare metals, gemstones, etc.), magnetic and gravitational fields, stratigraphy, and columns indicating relative size of deposits of most significant mineral resources. They also show multiple cross-sections of a region, offering geological pictures of the Earth’s crust to a depth of several tens of kilometers, tectonic lines, contour lines and elevation points, extensive color-coded legends of geological formations inherent to a particular map, and a cartographic bibliography identifying the authors, dates of publication and scales of other geological surveys used in preparing a particular map.

As you may know, geological maps unlike topographic maps, require extremely long lead times to produce and publish, as a result they are updated only very infrequently at a particular scale, so that maps produced in the 1970s or 1980s may still be the most recent mapping effort for a particular region. East View Cartographic was fortunate following the breakup of the Soviet Union in 1991 to be able to obtain thousands of these geological maps for all of the countries of the former Soviet Union, plus numerous Asian, African, and Middle Eastern countries. These geological maps are available in small scale ranging from 1:2,500,000 to 1:500,000, medium scale 1:200,000, and for some areas particularly in mineralogically rich regions of the former USSR like the Caucasus region, Ural mountains, and some areas of Siberia, and the Far East large scale 1:50,000 and 1:25,000 maps are available.

Russian geological maps are generally published in the Russian language. Fortunately the language barrier is easily overcome by virtue of the inherent intuitive nature of the maps, easily recognizable international geological and chemical symbols (almost always in the Roman alphabet) and the simple conversion of Cyrillic to Roman characters-many of which are in fact identical. In cases where translation is required, East View Cartographic has an in-house ability to provide this service.
