Central Iranian Range

Last updated

The Sahand-Bazman Volcanic and Plutonic Belt or the Sahand-Bazman Igneous Arc or the Central Iranian Range is a mountain range that is made by (both extrusive and intrusive) igneous and pyroclastic rocks. Located East and almost parallel to the Zagros Mountains, the Central Iranian Range is stretched in a north-west-southeast direction from Mount Sahand in Azerbaijan in the north-west to Mount Bazman in Baluchistan in the Southeastern part of Iran. [1] This range was mainly formed during the Tertiary volcanic and orogenic phase and especially in the Eocene volcanism and plutonism. [2] The Central Iranian Range or the Sahand-Bazman Volcanic Belt includes famous mountains such as the Sahand in East Azerbaijan Province, Mount Karkas in the Karkas Mountains and Mount Marshenan in Isfahan Province, the Jebal Barez, Mount Hezar and Mount Lalehzar in Kerman Province, and the Bazman in the Sistan va Baluchestan Province of Iran.

The Coast Mountains are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordillera—a Spanish term for an extensive chain of mountain ranges—that consists of an almost continuous sequence of mountain ranges that form the western backbone of North America, Central America, South America and Antarctica.

<span class="mw-page-title-main">Bazman</span> Volcano mountain in Iran

Bazman is a dormant stratovolcano in a remote desert region of Sistan and Baluchestan Province in southeastern Iran. A 500-m-wide crater caps the summit of the dominantly andesitic-dacitic volcano, the flanks of which are covered by monogenetic centres especially to the northwest. Bazman is a geologically young volcano which formed mainly in the Quaternary, with the oldest dated rocks being 11.7 million years old and the youngest 0.6 million years. Although no historic eruptions have been reported from Bazman, it does contain fumaroles. Thus Bazman may be regarded as dormant, rather than extinct, volcano. Its satellite cones have been the source of basaltic lava flows.

The Jebal Barez is a mountain chain in the Kerman Province of Iran. This mountain range stretches for some 100 km north-west to south-east, parallel to the Halil Rud, to the north-east of Jiroft and to the south-west of Bam, rising to a maximum elevation of 3,750 m. The mountains of this range are continued by other mountains such as Mount Shahsavaran and Mount Hudian to the south-east. They separate the plain of Hamun-e Jaz Murian from that of Namakzar-e Shahdad and Lut desert.

Made chiefly of Eocene andesite and pyroclastic rocks, Mount Lalehzar is situated in a central Iranian range, Sahand-Bazman volcanic range or belt, a mountain range which was formed mainly during Eocene volcanism and that stretches approximately from Sahand Volcano in the north-west of Iran to Bazman Volcano in the south-east of Iran.

Mount Bahr Aseman is a mountain located approximately 15 kilometres south of the town of Sarduiyeh and about 60 kilometres east of the city of Baft in Kerman Province in southeast Iran. With an elevation of 3,886 metres, the mountain is among high peaks of Iran.

Shahsavaran is a volcanic field in Iran. It covers an ellipse shaped area west of Bazman volcano. The field has erupted lava cones and lava flows, along with some explosive volcanic activity especially in the eastern part of the field. Volcanic rocks in the field are dominated by andesite, with subordinate basalt, dacite and rhyodacite. The volcanism has lasted from 12 million years ago to recent times, the 2010 Hosseinabad earthquake took place within the field but seems to be unrelated to volcanic activity.
