Central Iranian Range
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. This range was mainly formed during the Tertiary volcanic and orogenic phase and especially in the Eocene volcanism and plutonism.Geological Map of Iran, National Geoscience Database of Iran, www.ngdir.ir 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 Bazman ( fa, بزمان, also known ...

Extrusive Rock
Extrusive rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the Earth's atmosphere, atmosphere to fall back as Pyroclastic rock, pyroclastics or tuff. In contrast, intrusive rock refers to rocks formed by magma which cools below the surface.Jain, Sreepat (2014). ''Fundamentals of Physical Geology''. New Delhi, India: Springer. . The main effect of extrusion is that the magma can cool much more quickly in the open air or under seawater, and there is little time for the growth of crystals. Sometimes, a residual portion of the matrix (geology), matrix fails to crystallize at all, instead becoming a natural glass or obsidian. If the magma contains abundant Volatiles, volatile components which are released as free gas, then it may cool with large or small vesicles (bubble-shaped cavities) such as in pumice, scoria, or vesicular texture, vesicular basalt.

Jebal Barez
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 maximal 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. Etymology The root of the name of this mountain is identical to that of the Alburz in northern Iran and the Elbrus in the Caucasus, and therefore, it is likewise derived from an unattested Old Persian term *''Harā Brzatī'', cognate with Avestan ''Harā Bərəzaitī'' (see Harā Bərəzaitī), meaning "high watchpost". The more proper spelling of the name of this mountain is Albarez. ''Albarez'' is of the same construct as the names Alburz and Elbrus. The ancient Iranian people seem to have giv ...

Karkas Mountains
The Karkas mountain chain (Persian رشته كوه كركس ''Reshteh kuh-e Karkas'') is a mountain range which is located almost in central Iran. Having a northwest-southeast direction, it is stretched from Kashan to Ardestan for more than 100 kilometres. With an elevation of 3895 metres, the highest peak of the Karkas Mountains is Mount Karkas which is situated close to Natanz. Etymology Although in Persian ''karkas'' means vulture, it is possible that the name of this mountain chain is derived from the settlement activity of the ancient Kassites in the area, because in the ancient Assyrian language ''Kar-Kassi'' means "town or land of the Kassites" (modified interpretation after Roman Ghirshman, 1954). Geology The Karkas Mountains were formed mainly during the Eocene volcanism. Located in the Sahand-Bazman volcanic and plutonic belt, this mountain range is composed predominantly of the Eocene volcanic rocks of the Tertiary volcanism.

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...
