Laila Peak (Caucasus)
Mount Laila, Lahili ( ka, ლაჰილი), Lailchala ( ka, ლაილჭალა) but also known as Lahla, is the highest peak of the Svaneti Range Svaneti Range ( ka, სვანეთის ქედი) is an 85 km long sub-mountain range of the Greater Caucasus, in the Svaneti region of Georgia, located south of the main Caucasus ridge in a west–east direction. Devdariani G., Georgian ... in Georgia. The elevation of the summit is above sea level. Lahili's geological makeup mostly consists of Upper Palaeozoic-Triassic quartzite, metamorphic rock and sandstone. The mountain is covered by snow and ice. The northern slope of the summit contains several valley glaciers; notably, the Lahili Glacier descends from the summit down to an elevation of above sea level.''Georgian State (Soviet) Encyclopedia.'' 1983.

Svaneti Range
Svaneti Range ( ka, სვანეთის ქედი) is an 85 km long sub-mountain range of the Greater Caucasus, in the Svaneti region of Georgia, located south of the main Caucasus ridge in a west–east direction. Devdariani G., Georgian Soviet Encyclopedia , vol. 9, pages 310-311, 1985. The Svaneti Range runs along the border between the regions of Racha-Lechkhumi and Kvemo Svaneti and Samegrelo-Zemo Svaneti (North and South Svaneti) in the north of Georgia. It forms the watershed between the Enguri River (to the north and west) and the Tskhenistsqali (to the south). The right Tskhenistsqali tributary Cheledula separates the mountains from the further south Egrisi Range. The Svanetic Mountains reach a maximum altitude of 4009 m at the Lahili Peak. The ridge is partially glacier. Geology Svaneti Range is composed mainly of sedimentary ( mica, schist ) and partly of metamorphic rocks ( quartzite , slate ). Vegetation On the slopes grow subalpine Montane eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georgia (country)
Georgia (, ; ) is a transcontinental country at the intersection of Eastern Europe and Western Asia. It is part of the Caucasus region, bounded by the Black Sea to the west, by Russia to the north and northeast, by Turkey to the southwest, by Armenia to the south, and by Azerbaijan to the southeast. The country covers an area of , and has a population of 3.7 million people. Tbilisi is its capital as well as its largest city, home to roughly a third of the Georgian population. During the classical era, several independent kingdoms became established in what is now Georgia, such as Colchis and Iberia. In the early 4th century, ethnic Georgians officially adopted Christianity, which contributed to the spiritual and political unification of the early Georgian states. In the Middle Ages, the unified Kingdom of Georgia emerged and reached its Golden Age during the reign of King David IV and Queen Tamar in the 12th and early 13th centuries. Thereafter, the kingdom decl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
