[2] The plain is wider in the west (25-30 km), narrows in the southeast and ends around the village of Gendob.

The Gusar plain is mainly formed from thick gravel, sand and siltstones of the Upper Pliocene and Quaternary.

[1] When the Great Caucasus mountains rose strongly, the southern edge of the plain also began to rise and its surface became sloping.

To the southeast of the Gusar plain, between the Samur-Devachi lowland and the side ridge, there are low mountains formed by Paleogene and Neogene marine and continental sediments.

There are Telebi, Gaynarcha dashes, Rustov depression, Valvalachay, Karachay, Agjachay, and relatively wide, some box-shaped valleys of Gilgilchay in the southeast.
