Geological Survey Of India
The Geological Survey of India (GSI) is a scientific agency of India. It was founded in 1851, as a Government of India organization under the Ministry of Mines, one of the oldest of such organisations in the world and the second oldest survey in India after Survey of India (founded in 1767), for conducting geological surveys and studies of India, and also as the prime provider of basic earth science information to government, industry and general public, as well as the official participant in steel, coal, metals, cement, power industries and international geoscientific forums. History Formed in 1851 by East India Company, the organization's roots can be traced to 1836 when the "Coal Committee", followed by more such committees, was formed to study and explore the availability of coal in the eastern parts of India. David Hiram Williams, one of the first surveyors for the British Geological Survey, was appointed 'Surveyor of coal districts and superintendent of coal works, Be ...

Robert Mallet
Robert Mallet (3 June 1810 – 5 November 1881) was an Irish geophysicist, civil engineer, and inventor who distinguished himself in research on earthquakes and is sometimes called the father of seismology. His son, Frederick Richard Mallet was a geologist who worked in India. Early life Mallet was born in Dublin, on 3 June 1810, the son of factory owner John Mallet. He was educated at Trinity College, Dublin, entering it at the age of 16 and graduating in science and mathematics in 1830 at the age of 20. Career Following his graduation, he joined his father's iron foundry business and helped build the firm into one of the most important engineering works in Ireland, supplying ironwork for railway companies, the Fastnet Rock lighthouse, and a swing bridge over the River Shannon at Athlone. He also helped manufacture the characteristic iron railings that surround Trinity College and which bear his family name at the base. Mallet was elected to the Royal Irish Academy in 1832 at ...

Vindhya Range
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 Vindhyas have a great significance in Hindu mythology, Indian mythology and history. Several ancient texts mention the Vindhyas as the southern boundary of the ''Āryāvarta'', the territory of the ancient Indo-Aryan peoples. Al ...

Barren Island (Andaman Islands)
Barren Island is an island located in the Andaman Sea. It is the only confirmed active volcano in the Indian subcontinent, and the only active volcano along a chain of volcanoes from Sumatra to Myanmar. It is a part of the Indian Union territory of Andaman and Nicobar Islands, and lies about northeast of the territory's capital, Port Blair. History The first recorded eruption of the volcano dates back to 1787. Since then, the volcano has erupted more than ten times, with the most recent one being in 2020 . After the first recorded eruption in 1787, further eruptions were recorded in 1789, 1795, 1803–04, and 1852. After nearly one and a half century of dormancy, the island had another eruption in 1991 that lasted six months and caused considerable damage. The 1991 eruption was particularly harmful to the island's fauna. A team from the Geological Survey of India visited Barren Island on 8–9 April 1993 to assess the impact of the eruption on the distribution, habit, a ...

Ferdinand Stoliczka
Ferdinand Stoliczka (Czech written Stolička, 7 June 1838 – 19 June 1874) was a Moravian palaeontologist who worked in India on paleontology, geology and various aspects of zoology, including ornithology, malacology, and herpetology. He died of high altitude sickness in Murgo during an expedition across the Himalayas. Early life Stoliczka was born at the lodge ''Zámeček'' near Kroměříž in Moravia. Stoliczka, whose father was a forester who took care of the estate of the Archbishop of Olomouc, studied at a German Secondary school in Kroměříž. Although Stoliczka published 79 articles from 1859–1875, he never wrote anything in Czech. It is believed that he spoke German at home. In his Calcutta years he was an important figure in the German-speaking community there. Stoliczka studied geology and palaeontology at Prague and the University of Vienna under Professor Eduard Suess and Dr Rudolf Hoernes. He graduated with a Ph D from the University of Tübingen on 14 November ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Theobald
William Theobald (1829 – 31 March 1908) was a malacologist and naturalist on the staff of the Geological Survey of India serving in Burma, then a part of British India. Biography Very little is known of Theobald's early life. Theobald was referred to in official documents as "William Theobald, Junior". He arrived in Calcutta on the ship ''Hindostan'' via the Suez in March 1847 and worked as a volunteer in the coal exploration of the upper Damodar and Son valleys under David Williams. During this time Joseph Hooker visited him and they spent time together. Later Theobald became an assistant to John McClelland who took over the exploration from David Williams. He went to Burma in 1855 as a staff of the Geological Survey of India and took over the ''Pegu survey''. He returned Bengal on completion of the survey in 1873 to be appointed Deputy Superintendent of Bengal in 1876.Mabberley DJ (1985).

Sutlej
The Sutlej or Satluj River () is the longest of the five rivers that flow through the historic crossroads region of Punjab in northern India and Pakistan. The Sutlej River is also known as ''Satadru''. It is the easternmost tributary of the Indus River. The Bhakra Dam is built around the river Sutlej to provide irrigation and other facilities to the states of Punjab, Rajasthan and Haryana. The waters of the Sutlej are allocated to India under the Indus Waters Treaty between India and Pakistan, and are mostly diverted to irrigation canals in India like the Sirhind Canal, Bhakra Main Line and the Rajasthan canal. The mean annual flow is 14 million acre feet (MAF) upstream of Ropar barrage, downstream of the Bhakra dam. It has several major hydroelectric points, including the 1,325 MW Bhakra Dam, the 1,000 MW Karcham Wangtoo Hydroelectric Plant, and the 1,500 MW Nathpa Jhakri Dam. The drainage basin in India includes the states and union territories of Himachal Pra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allan Octavian Hume
Allan Octavian Hume, CB ICS (4 June 1829 – 31 July 1912) was a British civil servant, political reformer, ornithologist and botanist who worked in British India. He was the founder of the Indian National Congress. A notable ornithologist, Hume has been called "the Father of Indian Ornithology" and, by those who found him dogmatic, "the Pope of Indian Ornithology". As an administrator of Etawah, he saw the Indian Rebellion of 1857 as a result of misgovernance and made great efforts to improve the lives of the common people. The district of Etawah was among the first to be returned to normalcy and over the next few years Hume's reforms led to the district being considered a model of development. Hume rose in the ranks of the Indian Civil Service but like his father Joseph Hume, a radical member of parliament, he was bold and outspoken in questioning British policies in India. He rose in 1871 to the position of secretary to the Department of Revenue, Agriculture, and Commerce und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
