Ural Mountains, separating European Russia (physically though not politically) from Siberia, have been described at RUSSIA, Vol. IX. p. 33. The main axis of the series of ridges and plateaus consists of granite, diorite, syenite, porphyry, and schistose rocks. The mineral wealth is great, comprising gold, platinum, silver, copper, and iron, besides precious stones, malachite, &c. All the platinum of Russia is found here, and some two-thirds of its pig-iron.
