Jodhpur Group – Malani Igneous Suite Contact
Jodhpur Group-Malani Igneous Suite Contact of Aravalli range is a geological feature representing the last phase of igneous activity of Precambrian age in the Indian Subcontinent at the foot of the picturesque Mehrangarh Fort in Jodhpur city, the second largest city in Rajasthan after Jaipur. The uniqueness of the geological feature at Jodhpur prompted the Geological Survey of India (GSI) to declare the site as a National Geological Monument. Etymology Malani was the name of a district in the former state of Marwar (Jodhpur) where volcanic rocks were found and thus named as Malani beds (1877). This name underwent several changes over the years, known as Malani Volcanics Series (1902), Malani System (1933), the Malani Granite and Volcanic Suite(1968). Finally, the complete magmatic sequence has been named as the Malani Igneous Suite. The igneous suite marks the last phase of igneous activity of Precambrian age in the Indian subcontinent.

Jaisalmer
Jaisalmer , nicknamed ''The Golden city'', is a city in the north-western Indian state of Rajasthan, located west of the state capital Jaipur, in the heart of the Thar Desert. It serves as the administrative headquarters of Jaisalmer district. It is a former medieval trading center and the historic capital of the kingdom of Jaisalmer, founded in 1156 by Rawal Jaisal of the Bhati clan of Rajputs. Jaisalmer stands on a ridge of yellowish sandstone and is crowned by the World Heritage Site, Jaisalmer Fort, a sprawling hilltop citadel supported by 99 bastions. This fort contains a royal palace and several ornate Jain temples. Many of the houses and temples of both the fort and of the town below are built of finely sculptured yellow sandstone. The town has a population, including the residents of the fort, of about 78,000. Jaisalmer ranked 9th on Booking.com's Top 10 The Most Welcoming cities in the world.

Acidic
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen cation, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word ''acid'' is derived from the Latin , meaning 'sour'. An aqueous solution of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shales
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding pl ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary
Sedimentary rocks are types of rock formed by the cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies ( marine snow). Sedimentation may also occur when dissolved minerals precipitate from water solution. The sedimentary rock cover of the continents of the Earth's crust is extensive (73% of the ...

Vindhya
The Vindhya Range (also known as Vindhyachal) () is a complex, discontinuous chain of mountain ridges, hill ranges, highlands and plateau escarpments in west-central India. Technically, the Vindhyas do not form a single mountain range in the geological sense. The exact extent of the Vindhyas is loosely defined, and historically, the term covered a number of distinct hill systems in central India, including the one that is now known as the Satpura Range. Today, the term principally refers to the escarpment and its hilly extensions that runs north of and roughly parallel to the Narmada River in Madhya Pradesh. Depending on the definition, the range extends up to Gujarat in the west, Uttar Pradesh and Bihar in the north, and Chhattisgarh in the east. The average elevation of the Vindhyas is also dependent on different sources. The word Vindhya is derived from the Sanskrit word ''vaindh'' (to obstruct) and is in reference to a mythological story. The Vindhya range is also known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithological
The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples, or with low magnification microscopy. Physical characteristics include colour, texture, grain size, and composition. Lithology may refer to either a detailed description of these characteristics, or a summary of the gross physical character of a rock. Examples of lithologies in the second sense include sandstone, slate, basalt, or limestone. Lithology is the basis of subdividing rock sequences into individual lithostratigraphic units for the purposes of mapping and correlation between areas. In certain applications, such as site investigations, lithology is described using a standard terminology such as in the European geotechnical standard Eurocode 7. Rock type The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed directly from magma, which is a mixture of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mehrangarh Fort 5174627
Mehrangarh is a historic fort located in Jodhpur, Rajasthan, India. It stands on a hilltop, rising about above the surrounding plains, and the complex spans 1,200 acres (486 hectares). It was initially built around 1459 by the Rajput ruler of Rathore clan Rao Jodha, though most of the existing structure is from the 17th century built by his successors. The fort has seven gates, which includes main entrance Jai Pol (meaning 'victory gate'), built by Maharaja Man Singh to commemorate his victories over the Jaipur and Bikaner armies in 1806. The Fattehpol (), commemorates victory of Maharaja Ajit Singh over the Mughals. The English writer and Nobel Prize winner, Rudyard Kipling, described the fort as "''a palace that might have been built by Titans and colored by the morning sun.''" Within its boundaries are several palaces known for their intricate carvings and expansive courtyards, a Chamunda Mataji Temple, as well as a museum that houses various relics. A winding road leads ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Famine
A famine is a widespread scarcity of food caused by several possible factors, including, but not limited to war, natural disasters, crop failure, widespread poverty, an Financial crisis, economic catastrophe or government policies. This phenomenon is usually accompanied or followed by regional malnutrition, starvation, epidemic, and increased death, mortality. Every inhabited continent in the world has experienced a period of famine throughout history. During the 19th and 20th centuries, Southeast Asia, Southeast and South Asia, as well as Eastern Europe, Eastern and Central Europe, suffered the greatest number of fatalities due to famine. Deaths caused by famine declined sharply beginning in the 1970s, with numbers falling further since 2000. Since 2010, Africa has been the most affected continent in the world by famine. As of 2025, Haiti and Afghanistan are the two states with the most catastrophic and widespread states of famine, followed by Palestine (confined to Gaza Strip ...
