The settlement of Leyla-Tepe is located on the Karabakh plain at the northwestern outskirts of the small village of Eyvazlı, Agdam, close to the town of Quzanlı in the Aghdam District of Azerbaijan.

[4] Similar amphora burials in the South Caucasus are found in the Western Georgian Jar-burial culture, that is mostly of a much later date.

The ancient Poylu II settlement was discovered in the Aghstafa District of modern day Azerbaijan during the construction of the Baku–Tbilisi–Ceyhan pipeline.

The lowermost layer dates to the early fourth millennium BC, attesting a multilayer settlement of Leyla-Tepe culture.

[6] The excavation of these kurgans, located in Kaspi Municipality, in central Georgia, demonstrated an unexpectedly early date of such structures on the territory of Azerbaijan.

[7] The culture has also been linked to the north Ubaid period monuments,[8] in particular, with the settlements in the Eastern Anatolia Region (Arslantepe, Coruchu-tepe, Tepechik, etc.).

The settlement is of a typical Western-Asian variety, with the dwellings packed closely together and made of mud bricks with smoke outlets.

[9] An expedition to Syria by the Russian Academy of Sciences revealed the similarity of the Maykop and Leyla-Tepe artifacts with those found in 1988–2000 while excavating the ancient city of Tel Khazneh I, dating from the 4th millennium BC.

[14] The development of Leyla-Tepe culture in the Caucasus marked the early appearance of extractive copper metallurgy.

According to research published in 2017, this development that occurred in the second half of the 5th millennium BC preceded the appearance of metallurgy in Mesopotamia.

[9][16] In recent past, the development of copper metallurgy in the Caucasus was attributed to migrants from Uruk arriving around 4500 BCE,[17] or perhaps rather to the pre-Uruk traditions, such as the late Ubaid period, and Ubaid-Uruk phases.
