Murun Massif
Murun (russian: Мурун) is a mountain in the Olyokma-Chara Plateau, at the border of Irkutsk Oblast and Yakutia, Russian Federation. Geography A high summit is the highest point of the Murun Massif in the Olyokma-Chara Plateau, part of the South Siberian mountain system. The massif is about across and rises in the central/southern part of the plateau, above the right bank of the Chara, west of the valley of the Tokko, at the southwestern end of the Sakha Republic, bordering with Irkutsk Oblast, near the tripoint with Zabaykalsky Krai. The mountain is near Torgo, an abandoned settlement in Olyokminsky District.Google Earth The Murun peak is marked as a summit in the O-50 sheet of the Soviet Topographic Map. This same mountain, however, is a peak in the D-7 sheet of the Defense Mapping Agency Navigation charts.

Google Earth is a computer program that renders a 3D computer graphics, 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposition, superimposing satellite images, aerial photography, and geographic information system, GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and coordinates, or by using a Computer keyboard, keyboard or computer mouse, mouse. The program can also be downloaded on a smartphone or Tablet computer, tablet, using a touch screen or stylus to navigate. Users may use the program to add their own data using Keyhole Markup Language and upload them through various sources, such as forums or blogs. Google Earth is able to show various kinds of images overlaid on the surface of the earth and is also a Web Map Service client.

Mountains Of Irkutsk Oblast
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Frankamenite
Frankamenite is the fluorine-dominate variation of the rare mineral canasite with a general formula of K3Na3Ca5(Si12O30) ,(OH)sub>4·(H2O). Frankamenite belongs to the triclinic crystal system, with the bases of its structure containing Ca-Na mixed octahedra joined by octagonal tubes SiO4 of the composition (Si12O30). Frankamenite has six Ca-Na mixed positions distributed amongst these octahedra, reflecting its varying compositions. Frankamenite was named for the Russian mineralogist- crystallographer V. A. Frank-Kamentsky (1915–1994), who discovered the mineral. Frankamenite occurs in association with the rare mineral charoite, which is found only in the Murun Massif of the Olyokma-Chara Plateau, Aldan Shield, Sakha Republic, Yakutia, Siberia, Russia. Here, metasomatism enriches a syenite massif with potassium when it comes into contact with a limestone at around 200–250 °C. This metamorphic process produces a potassium feldspar Potassium feldspar refers to a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yuksporite
Yuksporite is a rare inosilicate mineral with double width, unbranched chains, and the complicated chemical formula . It contains the relatively rare elements strontium, titanium and niobium, as well as the commoner metallic elements potassium, calcium, sodium and manganese. As with all silicates, it contains groups of linked silicon and oxygen atoms, as well as some associated water molecules. Yuksporite is a member of the umbite group that has just two known members, umbite, , and yuksporite. It was first reported in 1922, from nepheline syenite occurrences in the Kola Peninsula, Russia, and named by Alexander Fersman for the locality, near Mount Yukspor. Unit cell Yuksporite was originally thought to be orthorhombic, space group unknown. In 2004, however, the structure was solved using synchrotron radiation and found to be monoclinic 2/m with space group P21/m. The monoclinic unit cell has two formula units per cell (Z = 2) and side lengths a = 7.126 Å, b = ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tausonite
Tausonite is the rare naturally occurring mineral form of strontium titanate: chemical formula: SrTiO3. It occurs as red to orange brown Cubic crystal system, cubic crystals and crystal masses. It is a member of the perovskite group. It was first described in 1982 for an occurrence in a syenite Intrusive rock, intrusive in Tausonite Hill, Murun Massif, Olyokma-Chara Plateau, Sakha Republic, Yakutia, geologically part of the Aldan Shield, Eastern-Siberian Region, Russia. It was named for Russian geochemist Lev Vladimirovich Tauson (1917–1989). It has also been reported from a fenite Dike (geology), dike associated with a carbonatite complex in Sarambi, Concepción Department (Paraguay), Concepción Department, Paraguay. and in high pressure metamorphic rocks along the Kotaki River area of Honshu Island, Japan.

Brookite
Brookite is the orthorhombic variant of titanium dioxide (TiO2), which occurs in four known natural polymorphic forms (minerals with the same composition but different structure). The other three of these forms are akaogiite (monoclinic), anatase (tetragonal) and rutile (tetragonal). Brookite is rare compared to anatase and rutile and, like these forms, it exhibits photocatalytic activity. Brookite also has a larger cell volume than either anatase or rutile, with 8 TiO2 groups per unit cell, compared with 4 for anatase and 2 for rutile.Anatase and Brookite .

Charoite
Charoite is a rare silicate mineral, first described in 1978. It was believed to be named after the Chara River, but due to the river being 70 km away from its discovery place, now it is believed to be named after the Russian word ''chary'', meaning magic or charms. When it was discovered, it was thought to be a fake, dyed purple to give it its striking appearance. Properties Charoite is translucent lavender to purple in color with a pearly luster. Charoite is strictly massive in nature, and fractures are conchoidal. It has an unusual swirling, fibrous appearance, sometimes chatoyant, and that, along with its intense color, can lead many to believe at first that it is synthetic or enhanced artificially. Though reportedly discovered in the 1940s, it was not known to most of the world until its description in 1978. It is said to be opaque and unattractive when found in the field; a fact that may have contributed to its late recognition. Charoite consists of oxygen (43.75%), ...

Aldan Shield
Aldan Shield (russian: Алданский щит) is a shield in Siberia. It is an exposed basement of the Siberian Craton. Together with the Anabar Shield further to the northwest, the Aldan Shield is one of the main features of the craton. The Aldan Shield geological region coincides geographically with parts of the Aldan Highlands and Olyokma-Chara Plateau, located at the southern end of the Sakha Republic and the eastern end of Irkutsk Oblast.Google Earth The exposed crust parts of the shield date back to the Archean and reflect the first phases of accretion of the crust. They only emerge in a few areas, the eastern and northern sectors of the shield being largely covered by sediments accumulated between the end of the Precambrian and the Cambrian, while in the western and southern regions they have undergone processes of tectonic rejuvenation that have brought about the formation of new structures above and below. On the Aldan Shield there is the only charoite deposit know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
