Alborz in the context of "Hyrcania"

The Arabian plate is a minor tectonic plate in the Northern and Eastern Hemispheres.

It is one of the three continental plates (along with the African and Indian plates) that have been moving northward in geological history and colliding with the Eurasian plate. This collision is resulting in a mingling of plate pieces and mountain ranges extending in the west from the Pyrenees, crossing Southern Europe to Iranian plateau, forming the Alborz and the Zagros Mountains, to the Himalayas and ranges of Southeast Asia.

The Alpide belt or Alpine-Himalayan orogenic belt, or more recently and rarely the Tethyan orogenic belt, is a seismic and orogenic belt that includes an array of mountain ranges extending for more than 15,000 kilometres (9,300 mi) along the southern margin of Eurasia, stretching from Java and Sumatra, through the Indochinese Peninsula, the Himalayas and Transhimalayas, the mountains of Iran, Caucasus, Anatolia, the Mediterranean, and out into the Atlantic.

It includes, from west to east, the major ranges of the Atlas Mountains, the Alps, the Caucasus Mountains, Alborz, Hindu Kush, Karakoram, and the Himalayas. It is the second most seismically active region in the world, after the circum-Pacific belt (the Ring of Fire), with 17% of the world's largest earthquakes.

Fraxinus excelsior, known as the ash, or European ash or common ash to distinguish it from other types of ash, is a flowering plant species in the olive family Oleaceae. It is native throughout mainland Europe east to the Caucasus and Alborz mountains, and west to Great Britain and Ireland, the latter determining its western boundary. The northernmost location is in the Trondheimsfjord region of Norway. The species is widely cultivated and reportedly naturalised in New Zealand and in scattered locales in the United States and Canada. The wood has many uses as it is flexible, workable, strong and lightweight.

Tangeh-ye Vashi (Persian: تنگه واشی) (35°52′33″N 52°43′37″E / 35.87583°N 52.72694°E / 35.87583; 52.72694) is a gorge and mountain pass in the Alborz mountain range, Iran. The narrow gorge was created by a perennial stream which comes down from a series of waterfalls upstream. Slightly lower, in a hilly area, the stream provided a patch of grazing land within the mountains.

Tālīsh (Talysh: Tolış; Azerbaijani: Talış; Persian: تالش, romanized: Tālesh) is a region in the southwestern coast of the Caspian Sea. It is a homeland of the indigenous Talysh people, who inhabit the region and speak the Talysh language. The territory and the language set apart Talish from its neighbors.

Talish is now divided between Azerbaijan and Iran. It stretches north from the Sefīd-Rūd river, which cuts through the Alborz mountains in Iran's Gilan province, to the Aras river in the south of the Republic of Azerbaijan.

Northern Iran (Persian: شمال, romanized: Shomal, lit. 'North'), is a geographical term that refers to a relatively large and fertile area, consisting of the southern border of the Caspian Sea and the Alborz mountains.

It includes the provinces of Gilan, Mazandaran, and Golestan (ancient kingdom of Hyrcania, medieval region of Tabaristan). The major provinces, Gilan and Mazandaran, are covered with dense forests, snow-covered mountains and impressive sea shores.

Mazanderanis (Mazanderani: مازرونی مردمون), also known as the Tabari people or Tabarestani people (Mazanderani: توری مردمون or تبری مردمون), are an Iranian people who are indigenous to the Caspian Sea region of Iran. They are also referred to as Mazanis for short. They inhabit the southern coast of the Caspian Sea and are part of the historical region known as Tabaristan. The Alborz Mountains mark the southern boundary of the area settled by the Mazanderani people.
