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 given ...

Plutonism
Plutonism is the geologic theory that the igneous rocks forming the Earth originated from intrusive magmatic activity, with a continuing gradual process of weathering and erosion wearing away rocks, which were then deposited on the sea bed, re-formed into layers of sedimentary rock by heat and pressure, and raised again. It proposes that basalt is solidified molten magma. The theory lead to plutonic (intrinsic) rock classification, which includes intrinsic igneous rocks such as gabbro, diorite, granite and pegmatite. The name ''plutonism'' references Pluto, the classical ruler of the underworld and the Roman god of wealth. A main reason Pluto was incorporated into the classification was due to the plutonic rocks commonly being present in gold and silver ore deposits (veins). The ''Oxford English Dictionary'' traces use of the word "plutonists" to 1799, and the appearance of the word ''plutonism'' to 1842. Abbé Anton Moro, who had studied volcanic islands, first proposed the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanism
Volcanism, vulcanism or volcanicity is the phenomenon of eruption of molten rock (magma) onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics, and volcanic gases erupt through a break in the surface called a vent. It includes all phenomena resulting from and causing magma within the crust or mantle of the body, to rise through the crust and form volcanic rocks on the surface. Magmas, that reach the surface and solidify, form extrusive landforms. Volcanic processes Magma from the mantle or lower crust rises through the crust towards the surface. If magma reaches the surface, its behavior depends on the viscosity of the molten constituent rock. Viscous (thick) magma produces volcanoes characterised by explosive eruptions, while non-viscous (runny) magma produce volcanoes characterised by effusive eruptions pouring large amounts of lava onto the surface. In some cases, rising magma can cool and solidify without reaching the surface. Inste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bazman
Bazman ( fa, بزمان, also known as Kuh-e Bazman) is a dormant stratovolcano in a remote desert region of Sistan and Baluchestan Province in south-eastern 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. Its satellite cones have been the source of basaltic lava flows. Bazman volcano is part of a volcanic arc in southeastern Iran, the Makran volcanic arc. At this arc, shallow subduction has generated an arc of volcanic activity which includes Bazman, Taftan and Koh-i-Sultan volcanoes. Bazman has been affected by heavy erosion. The flan ...

Sahand
Sahand ( fa, سهند), is a massive, heavily eroded stratovolcano in East Azerbaijan Province, northwestern Iran. At , it is the highest mountain in the province of East Azarbaijan. Sahand is one of the highest mountains in Iranian Azerbaijan, in addition to being an important dormant volcano in the country. The Sahand mountains are directly south of Tabriz, the highest peak of which is Kamal at an elevation of . Approximately 17 peaks can be accounted for as being over in height. Due to the presence of a variety of flora and fauna, the Sahand mountains are known as the bride of mountains in Iran. The absolute dating of Sahand rocks indicates that this volcano has been sporadically active from 12 million years ago up to almost 0.14 million years ago. Sahand is made chiefly of dacite and associated felsic rocks. Winter sports Sahand Ski Resort is on the northern foothills of the mountain and near the city of Tabriz. In the complex the Sahand Skiing Stadium has a 1200 meters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Intrusive Rock
Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form '' intrusions'', such as batholiths, dikes, sills, laccoliths, and volcanic necks.Intrusive RocksIntrusive rocks accessdate: March 27, 2017.Igneous intrusive rocks, accessdate: March 27, 2017.Britannica.comintrusive rock , geology , Britannica.com accessdate: March 27, 2017. Intrusion is one of the two ways igneous rock can form. The other is extrusion, such as a volcanic eruption or similar event. An intrusion is any body of intrusive igneous rock, formed from magma that cools and solidifies within the crust of the planet. In contrast, an ''extrusion'' consists of extrusive rock, formed above the surface of the crust. Some geologists use the term plutonic rock synonymously with intrusive rock, but other geologists subdivide intrusive rock, by crystal size, into coarse-grained plutonic rock (typically formed deeper in the Earth's crust in batholiths or stocks) an ...

Extrusive
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 atmosphere to fall back as 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 fails to crystallize at all, instead becoming a natural glass or obsidian. If the magma contains abundant 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 basalt. Other examples of extrusive rocks are rhyolite and andesite. Texture The texture of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic 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 13C in the atmosphere was exceptionally low in comparison with the more common isotope 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 Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Burnes
Captain Sir Alexander Burnes (16 May 1805 – 2 November 1841) was a Scottish explorer, military officer, and diplomat associated with the Great Game. He was nicknamed Bokhara Burnes for his role in establishing contact with and exploring Bukhara. His memoir, ''Travels into Bokhara'', was a bestseller when it was first published in 1835. Early life Burnes was born on 16 May 1805 in Montrose, Scotland, as the fourth son of James Burnes (1780–1852) the local provost, who was first cousin to the poet Robert Burns. His brother was the doctor and surgeon James Burnes. At the age of sixteen, Alexander joined the army of the East India Company and while serving in India, he learned Urdu and Persian, and obtained an appointment as interpreter at Surat in 1822. He was transferred to Kutch in 1826 where he was based at Bhuj for three years. As assistant to the political agent, he took an interest in the history and geography of north-western India and the adjacent ...
