The capital of the Russian Federation is Moscow. It is the largest political, administrative, scientific,economic, educational and cultural center of the country.The place where we live is Zabaikaliye or Zabaikalsky territory. It is situated in Eastern Siberia and is the link between Siberia and the Russian Far East. The climate of our region is sharp-continental with sunny and hot summers and severe, snowless winters. The fauna of Zabaikaliye is very rich. We can find the bear, the wolf, the deer, the fox, the sable and other mammals of the taiga. There are several mineral springs in our region, such as the Kuka, the Molokovka and the Darasun. They are very curative.The principal industries on the Zabaikalsky territoryare mining, timber and wood-processing, engineering, food and light industries. The region is very rich in deposits of ferrous and non-ferrous metals, gold, molybdenum, beryllium, polymetallic ore, coal, graphite, magnetic ores, uranium and radon springs.Ore deposits are found in the Chara Zone, the Chinei Zone and the Kruchininskoye.
