General information

is typified by relief of different kinds and complexity. Over 50% of the country's area consists of the mountain ridges, crests, yailas and plateaus rise up to hypsometric levels of 400–1,000 m (including the Middle and Lower lowlands), in some places (Talish, Jeyranchol-Ajinohur and Langabiz-Alat foreranges) up to 100–120 m, as well as 0–50 m up ( Gobustan, Absheron) the remaining parts of which are plains and lowlands. Hypsometric marks within the Caucasus region vary in the range from about -28 m at the

Quantitative distribution

The quantitative area distribution of Azerbaijan according to the hypsometric levels is as follows: * 18% is located below the ocean level. * 24% has hypsometric marks ranging from 0 to 200 m. * 15.5% is covered by areas which elevation ranges from 200 to 500 m. * 15.5% is covered by areas which elevation marks ranges from 500 to 1,000 m. * 19.5% is covered by areas which elevation ranges from 1,000 to 2,000 m high. * 6.5% is covered by areas which elevation ranges from 2,000 to 3,000 m. * 1% is covered by areas which elevation marks are over 3,000 m high. The average elevation is 384 m high. Principle orographic units of Azerbaijan consist of the Caucasus mountain system, Samur-Davachi lowland (in conjunction with Gusar inclined plain), Kur River lowland, Minor Caucasus, and Talish mountain systems.

Caucasus mountains system

The southeast part of the Caucasus mountain region is located within Azerbaijan. The basic orographic elements of this part of the Caucasus system are Major Caucasus system or Watershed Ridge and the Lateral ridge. Major Caucasus ridge constitutes large portion of the Caucasus system and extends southeast off Tinov-Rosso elevation (3,385 m) is located at

Major Caucasus

The Major Caucasus or Watershed Ridge is not crossed with any river valleys and therefore it is also called Watershed Ridge. Most part of the ridge elevation is over 3,000 m high, and only in its central part it exceeds 4,000 m height; which are: * Bazardüzü – 4,466 m * Tufandagh – 4,191 m * Bazaryurd – 4,126 m Beginning from Babadagh peak (located at 3629m, means "Father Mountain") the same ridge elevation gradually goes down and becomes wider. Starting from Dubrar elevation (2,205 m), Major Caucasus ridge plunges northeastward towards the Caspian Sea like expanded fan having been cut by river valleys into separate ridges like Gadi-Kurkachidagh, Aladagh, Kemchi and others.

Lateral Ridge

The same ridges are further divided into smaller and lower ridges to pass into low elevation mountain region named Gobustan, and further on into Absheron Peninsula. North off and parallel to the Great Caucasus ridge there is a southeast trending ridge called Lateral, of which Azerbaijan section starts from the Shahdagh (located at 4,243 m, means "Kings Mountain") extending and getting lower southeastward and terminates at Beshbarmag (located at 546 m, Besh Barmag Mountain means "Five Finger Mountain") pinnacle. The southeastern section of lateral Ridge Tengi-Beshbarmagh is a medium and low-altitude mountain erosion-denudation relief. The relief of this part consists of the

Talabi-Gaynarja elevation

Northeast off and parallel to the Lateral ridge there is Talabi-Gaynarja elevation, which elevation ranges from 1,000–1,100 m in the west down to 150–200 m in the east. Ridges and elevations are divided from each other by valleys and intermontane troughs (Shahnabad, Khinalyg, Erphee, Gonagcand, Kaltan, Gilgilchay, Tigchay, Rustov, Perebedil and others). The southern flank of the Great Caucasus ridge descended to Alazan-Ayrichay valley (in some sources Alazan-Haftaran valley, whereas in others it is considered one of the Kur River valley parts) that in some places is parallel to the mentioned ridge. Said above valley begins from

. Nialdagh ridge which elevation reaches up to 2,100 m high is extended parallel to the Great Caucasus one apart through Lahidge valley. They characterized by the middle-altitude mountain denudation relief.

Jeirankechmez depression

The depression is followed by linearly extended folded ridges and dome-shaped elevations substituting with wide synclinal valleys and constitutes in plan to the eastern part of the Shamakhy-Gobustan syncline. The northwestern section of the Jeyrankechmez corresponds to the topography of the Baku age alluvial-proluvial plain. The southeastern part of the depression characterized by younger abrasion-accretion marine plain and relief composed of the large brachyanticline elevations and broken by lengthwise ruptures.
