Russia is the largest country in the world; it covers a vast amount of topographically varied territory, including much that is inaccessible by conventional modes of transportation. The traditional centers of economic activity are almost exclusively located in the more hospitable European part of Russia, which once offered considerable coal and natural gas to drive heavy industry (see fig. 7). But the European fuel base was largely depleted by the 1980s, forcing Russia to rely on Siberian deposits much farther from the industrial heartland.
Russia is one of the world's richest countries in raw materials, many of which are significant inputs for an industrial economy. Russia accounts for around 20 percent of the world's production of oil and natural gas and possesses large reserves of both fuels. This abundance has made Russia virtually self-sufficient in energy and a large-scale exporter of fuels. Oil and gas were primary hard-currency earners for the Soviet Union, and they remain so for the Russian Federation. Russia also is self-sufficient in nearly all major industrial raw materials and has at least some reserves of every industrially valuable nonfuel mineral--even after the productive mines of Ukraine, Kazakstan, and Uzbekistan no longer were directly accessible. Tin, tungsten, bauxite, and mercury were among the few natural materials imported in the Soviet period. Russia possesses rich reserves of iron ore, manganese, chromium, nickel, platinum, titanium, copper, tin, lead, tungsten, diamonds, phosphates, and gold, and the forests of Siberia contain an estimated one-fifth of the world's timber, mainly conifers (see fig. 8; Environmental Conditions, ch. 3).
The iron ore deposits of the Kursk Magnetic Anomaly, close to the Ukrainian border in the southwest, are believed to contain one-sixth of the world's total reserves. Intensive exploitation began there in the 1950s. Other large iron ore deposits are located in the Kola Peninsula, Karelia, south-central Siberia, and the Far East. The largest copper deposits are located in the Kola Peninsula and the Urals, and lead and zinc are found in North Ossetia.
