Amur-Zeia Plateau

 

a plateau in Amur Oblast, RSFSR, in the basins of the Amur and Zeia rivers and two Zeia tributaries, the Selemdzha and Urkan. The plateau has an elevation of about 300 m, and the highest point is 904 m. Low ridges and hills predominate; in the Amur Valley, the plateau area is very rugged. The crystalline rock of the base is covered by beds of sands and clays which were deposited in Neogenic lakes and in the ancient channels of the Amur and Zeia rivers. Larch and pine forests and birch groves are found; in the south, thickets of dwarf oak are typical. There are many swamps.
