The Angara Range (ru|Ангарский кряж) is a mountain range in Krasnoyarsk Krai and Irkutsk Oblast, Russia, part of the Central Siberian Plateau.[1]
There are large iron ore deposits in the area of the Angara Range.
The Angara Range is made up of hills of moderate height roughly aligned from southwest to northeast in the southeastern part of the Central Siberian Plateau. It stretches for about 800km (500miles) from the northern foothills of the Eastern Sayan in the east to the upper basin of the Lower Tunguska river. To the east and southeast the range smoothly merges with the higher Lena-Angara Plateau. The highest summit is an unnamed 1022m (3,353feet) high peak located in the southern part. The middle stretch of the range has lower maximum altitudes, which increase in the northern part where 912m (2,992feet) high Irina Peak is located.[2] [3] [4]
The ridges of the range are roughly parallel, They have gently sloping interfluves, composed of Lower Paleozoic carbonate rocks, terrigenous sediments and stratigraphic traps.[5]
The southern and central areas of the range are drained by a few left and right tributaries of the Angara which form small waterfalls and rapids when crossing the trap zones. The Lower Tunguska and Stony Tunguska rivers, right tributaries of the Yenisei, originate in the northern slopes.[2] [3] [4]
The hills of the range are mainly covered with larch taiga in the northeastern part of the range, with pine, fir and Siberian Pine in the southwestern section.[5]
