The '''Aravalli Range''' (also spelled ''Aravali'') is a mountain range in [[North India|Northern]]-[[

The Aravalli Range, an eroded stub of ancient mountains, is believed to be the oldest range of [[fold mountains]] in India.<ref name=ara6>Roy, A. B. (1990). Evolution of the Precambrian crust of the Aravalli Range. Developments in Precambrian Geology, 8, 327–347.</ref> The [[natural history]] of the Aravalli Range dates back to times when the [[Indian Plate]] was separated from the [[Eurasian Plate]] by an ocean. The Proterozoic Aravalli-Delhi [[orogenic belt]] in northwest India is similar to the younger Himalayan-type orogenic belts of the [[Mesozoic]]-[[Cenozoic]] era (of the [[Phanerozoic]]) in terms of component parts and appears to have passed through a near-orderly [[Supercontinent cycle#Description|Wilson supercontinental cycle of events]]. The range rose in a [[Precambrian]] event called the [[Tectonic evolution of the Aravalli Mountains#Aravalli Orogeny|Aravalli]]-[[Tectonic evolution of the Aravalli Mountains#Delhi Orogeny|Delhi Orogen]]. The Aravalli Range is a northeast–southwest trending orogenic belt located in the northwestern part of Indian Peninsula. It is part of the [[Indian Shield]] that formed from a series of [[craton]]ic collisions.<ref name=":0">Mishra, D.C.; Kumar, M. Ravi. Proterozoic orogenic belts and rifting of Indian cratons: Geophysical constraints. Geoscience Frontiers. 2013 March. 5: 25–41.</ref> In ancient times, Aravalli were extremely high but since have worn down almost completely from millions of years of [[weathering]], whereas the [[Himalayas]], young fold mountains, are still continuously rising. Aravalli have stopped growing higher due to the cessation of upward thrust caused by the [[tectonic plates]] in the [[Earth's crust]] below them. The Aravalli Range joins two of the ancient

Line 132:
The stratigraphic classification of the Aravalli Range can be divided into the following parts (north to south direction):
* The Archean basement is a banded gneissic complex with [[schists]] (medium grade metamorphic rock), [[gneiss]]es (high grade regional metamorphic rock), [[Peninsular Gneiss|composite gneiss]] and [[quartzite]]s. It forms the basement rock for both the Delhi Supergroup and the Aravalli Supergroup.
* Aravalli Supergroup: The Aravalli supergroup passes through [[Rajasthan]] state, dividing it into two halves, with three-fifths of Rajasthan on the western side towards the [[Thar Desert]] and two-thirds on the eastern side consisting of the catchment area of [[Banas River|Banas]] and [[Chambal River|Chambal]] rivers bordering the state of [[Madhya Pradesh]].{{Clarify |date=September 2020 |reason=Three-fifths and two-thirds add up to more than one.}} [[Guru Shikhar]], the highest peak in the Aravalli Range at {{convert|5650|ft}} in [[Mount Abu]] of Rajasthan, lies near the south-western extremity of the Central Aravalli range, close to the border with [[Gujarat]] state. The southern ''Aravalli Supergroup'' enters the northeast of [[Gujarat]] near [[Modasa]] where it lends its name to the [[Aravalli district]], and ends at the centre of the state at [[Palanpur]] near [[Ahmedabad]].

The geographic features of Rajasthan are the [[Thar Desert]] and the [[Aravalli Range]], which runs through the state from southwest to northeast, almost from one end to the other, for more than {{convert|850|km}}. [[Mount Abu]] lies at the southwestern end of the range, separated from the main ranges by the [[West Banas River]], although a series of broken ridges continues into [[Haryana]] in the direction of [[Delhi]] where it can be seen as outcrops in the form of the [[Raisina Hill]] and the ridges farther north. About three-fifths of Rajasthan lies northwest of the Aravallis, leaving two-fifths on the east and south direction.

'''"The Great Green Wall of Aravalli"''' is a proposed 1,600 km long and 5 km wide green ecological corridor along Aravalli range from Gujarat to Delhi, it will be connected to [[Sivalik Hills|Shivalik]] hill range and 1.35 billion (135 crore) new native trees will be planted over 10 years to rehabilitate the forest cover in this area. To be implemented on a concept similar to the [[Great Green Wall (Africa)|Great Green Wall]] of [[Sahara]] in Africa, it will act as a buffer against pollution, 51% of which is caused by the industrial pollution, 27% by vehicles, 8% by [[Stubble burning#Stubble burning in India|crop burning]] and 5% by [[Diwali|diwali fireworks]].<ref name=wall1>[https://indianexpress.com/article/cities/ahmedabad/want-govt-to-build-1600-km-green-wall-along-aravalli-says-activist-vijaypal-baghel-6182069/ Want govt to build 1600 km green wall along Aravalli], Indian Express, 24 December 2019.</ref> It was proposed several times form the 1990s, but as of 2024 the project is still in the planning stage.<ref>https://www.youtube.com/watch?v=g59CelQPX74</ref>

This corridor is an important habitat for the Indian [[leopard]]s and [[jackal]]s of Aravalli. In January 2019, the [[Wildlife Institute of India]] announced that they will undertake the survey of leopard and wildlife, using pugmarks and trap cameras, subsequently, leopards and jackals will be tracked via the [[Wildlife radio telemetry|radio collars]]. Urban development, especially the highways and railways bisecting the Aravalli range and wildlife corridor in several places pose a great risk. Large parts of Aravalli are legally and physically unprotected, with no wildlife passages and little or no wildlife conservation work resulting in deaths of over 10 leopards in 4 years between January 2015 to January 2019.<ref name=hitunp1>[https://www.hindustantimes.com/india-news/death-proof-of-leopardlife-in-asola-sanctuary/story-XFkBEhQ05I2vew9M1KDSFI.html Death, proof of leopard life in Asola sanctuary], Hindustan Times, 31 January 2019.</ref><ref name=today1>[https://www.indiatoday.in/india/story/10-month-old-leopard-dead-haryana-gurugram-faridabad-expressway-1442898-2019-01-30 10-month-old leopard found dead on Gurugram-Faridabad Expressway], ''India Today'', 31 January 2019.</ref><ref>[https://timesofindia.indiatimes.com/city/gurgaon/leopard-killed-in-accident-on-gurugram-faridabad-road/articleshow/67755160.cms Leopard killed in accident on Gurugram-Faridabad road], ''Times of India'', 30 January 2019.</ref>
The Haryana side of the Gurugram-Faridabad Aravalli hill forests lack availability of water due to which wild animals are seldom seen there. The Government of Haryana used drones for aerial surveys and dug 22 [[ephemeral]] pits in 2018 to store the rainwater which became dry during the summer months. In January 2019, the government announced the plan to make the pit [[Perennial stream|perennial]] by connecting those with pipelines from the nearby villages.<ref name=scar1>[https://timesofindia.indiatimes.com/city/chandigarh/leopards-keep-away-from-haryana-side-of-asola-due-to-scarcity-of-water/articleshow/67777130.cms Leopards keep away from Haryana side of Asola due to scarcity], ''Times of India'', 1 February 2019.</ref>
Human activity, such as unplanned urbanization and polluting industrial plants, also pose a great threat.
