Alborz

The name Alborz is derived from Harā Barazaitī, a legendary mountain in the Avesta, the main text of Zoroastrianism.

Bṛzatī is the feminine form of the adjective bṛzant- "high", the ancestor of modern Persian bouland and BarzBerazandeh, cognate with Sanskrit Brihat.

All these names reflect the same Iranian language compound, and have been speculatively identified, at one time or another, as the legendary mountain Hara Berezaiti of the Avesta.

It is only 60–130 km wide and consists of sedimentary series dating from Upper Devonian to Oligocene, prevalently Jurassic limestone over a granite core.

Very thick beds of Tertiary (mostly Eocene) green volcanic tuffs and lavas are found mainly in the southwestern and south-central parts of the range.

The collisions finally caused the folding of the Upper Paleozoic, Mesozoic, and Paleogene rocks and the Cenozoic (chiefly the Eocene) volcanism, to form the Alborz Mountains, primarily during the Miocene.

Stone artifacts and animal fossils were discovered by a group of archaeologists of the Department of Paleolithic of the National Museum of Iran and ICHTO of Gilan.

[2] During Middle Paleolithic period, Neanderthals were most probably were present in the region as their fossil have been found at northwest of Alborz, in the Azykh Cave.

[3] Evidence for Modern human comes from a river side site called Garm Roud in the Mazandaran Province which dates back to about 30,000 years ago.
