[Note 86] p. 514.—Geology of the Altai.
“In the Altai the mountains are built up of granites, syenites, and diorites covered with metamorphic slates belonging to the Laurentian, Silurian, Devonian, and Carboniferous periods. The Jurassic strata on the outskirts are all fresh-water deposits, and contain coal.”
“The Altai Mines (12,000 men) yielded in 1881, 16,670 lbs. of silver, 13,140 cwts. lead, 6708 cwts. copper, 3200 cwts. iron, 240,000 cwts. coal, and 320,000 cwts. salt.”
