Aldan Highlands: description, features, photo
Where is the Aldan Highlands and what is it? It is to these questions that you can get answers if you read the material outlined in this article.
On the territory of the Republic of Sakhais the highlands, which is called Aldan. This form of relief is an average elevation. If you look at the map, it is located on the northern outskirts of Stanovoi Ridge, between two large rivers of Siberia - Uchur and Olekma.
The Aldan Plateau is aa tectonic shield of the Precambrian period. It is located on the Siberian platform. The structure of the tectonic shield consists mainly of Proterozoic shales and gneisses. Practically everywhere in the territory of the uplands, crystalline basements appear on the surface, which are represented by gneisses, quartzites, and marbles. These crystalline rocks are overlain by layers of fine granite. It is worth noting that each of them was formed in different geological periods.
The Aldan Plateau has smooth, smooth slopes. Only its northern side is subject to a small laying of the foundation.
Features of the relief
The relief of the Aldan Highlands itself is represented bylow stolovo-stepped hills. Their average height is 800-1200 m. The highest point is the mountain, which has no name, with the height of 2306 m. The ancient volcanic activity had a big influence on the formation of the stepped relief of the upland. The fact that in this place volcanoes often erupted, the remaining traces of their activity speak.
Orographically the highlands are stretched in latitudinal direction. Throughout its length, there are lines of tectonic faults in the platform, in which river valleys are located.
Minerals of the Aldan Plateau
The terrain of this highland is poorly understood. An obstacle to this is the severe climate and permafrost zones. But despite this, in the last century rich mineral deposits were found on this territory. Now the Aldan Highlands - a place that is a "golden vein" for Yakutia. In the 20-ies. the last century, quite by accident, the Yakut hunter near the stream found gold deposits. As it turned out later, these are the largest gold-mining basins of the Russian Federation.
In addition to these deposits on the local territoryCopper and iron ores, mica and rock crystal have been explored and mined. Also, the Aldan Highlands are rich in coal deposits. Its deposits are on the southern slope. However, coal mining here is difficult due to weather conditions.
