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.

Geographical position

On the territory of the modern Republic of Sakha is a highland, 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.

Characteristic

The Aldan Plateau is a 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 form on the surface, which are represented by gneisses, quartzites, and marbles. These crystalline rocks overlap with layers of fine granite. It is worth noting that each of them was formed in different geological periods.

The Aldan Highlands have 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 by low 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 elongated in a latitudinal direction. Throughout its length, there are lines of tectonic faults of 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 in spite of this, in the last century rich deposits of minerals were found on this territory. Now the Aldan plateau is 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 basins of the Russian Federation.

In addition to these deposits, copper and iron ores, mica and rock crystal have been explored and extracted on the local territory. 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.
