* Metamorphic rocks: These rocks, formed from existing rocks under intense heat and pressure, are the most prevalent in the Altai. They include:
* Schists: These rocks are often layered and have a platy texture, formed from shale or other sedimentary rocks.
* Gneisses: These rocks are coarsely crystalline and often have a banded appearance, formed from granite or other igneous rocks.
* Marble: This metamorphic rock is formed from limestone and is known for its beauty and durability.
* Igneous rocks: These rocks are formed from molten rock (magma or lava) and are found in the Altai in smaller quantities than metamorphic rocks. They include:
* Granite: This igneous rock is hard, durable, and often forms large intrusions.
* Basalt: This igneous rock is dark-colored and fine-grained, often found in volcanic regions.
* Sedimentary rocks: These rocks are formed from the accumulation and cementation of sediment, and are relatively less common in the Altai compared to the other rock types. However, they do exist in certain areas, including:
* Limestone: This sedimentary rock is formed from the accumulation of marine organisms and is found in some areas of the Altai.
* Sandstone: This sedimentary rock is formed from the accumulation of sand grains and can be found in certain regions.
The specific rock types and their distribution within the Altai Mountains vary depending on the location and geological history of the region. However, the dominant rock types are metamorphic and igneous, showcasing the immense geological forces that have shaped this impressive mountain range.
