Lonar Lake, also known as Lonar crater, is a notified National Geo-heritage Monument, saline, soda lake, located at Lonar in Buldhana district, Maharashtra, India.Lonar Lake is an astrobleme created by a meteorite impact during the Pleistocene Epoch. The lake island in its centre is known as Ren-Levasseur Island, and its highest point is Mount Babel.The structure was created 214 (1) million years ago, in the Late Triassic, by the impact of a meteorite 5 km (3 mi) in diameter. Complex craters are a type of large impact crater morphology.. Description. Above a certain threshold size, which varies with planetary gravity, the collapse and modification of the transient cavity is much more extensive, and the resulting structure is called a complex crater.The collapse of the transient cavity is driven by gravity, and involves both the uplift of the central region and the It is about 30 km (19 mi) south-east of Kumasi, the capital of Ashanti, and is a popular recreational area.There are about 30 villages near the crater lake of Lake Bosumtwi, with a combined population of about 70,000. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not The crater averages about 875 metres (2,871 ft) in diameter, 60 metres (200 ft) from rim to present crater floor. The Witwatersrand Basin is a largely underground geological formation which surfaces in the Witwatersrand. These planes, which show up as lines under a microscope, are called planar deformation features (PDFs), or shock lamellae. It is estimated that the meteorite that formed it was about 15 metres (49 ft) in diameter It holds the world's largest known gold reserves and has produced over 40 000 tonnes (1.3 10 9 ozt), which represents about 22% of all the gold accounted for above the surface. It is located in the Tajik National Park in the Pamir Mountains in Tajikistan ISBN 978-1-920843-96-0 (pbk.) Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. The crater averages about 875 metres (2,871 ft) in diameter, 60 metres (200 ft) from rim to present crater floor. The Vredefort impact structure / f r d f r t / is the largest verified impact structure on Earth. The Russian Academy of Sciences lists the feature as a potential impact crater. Manicouagan Reservoir (also Lake Manicouagan) is an annular lake in central Quebec, Canada, covering an area of 1,942 km 2 (750 sq mi). According to the hypothesis, during this interval, a disproportionately large number of asteroids collided with the early terrestrial planets in the The crater, which has since been eroded away, was around 160300 km (100200 mi) across when it was formed. South Africa produces in excess of 255 million tonnes of coal (2011 estimate) and consumes almost three-quarters of that domestically. [citation needed]Henbury is one of five meteorite impact sites in Australia with remaining meteorite fragments and one of the world's best preserved examples of a small crater field. 1082: Karakul, Qarokul (Kyrgyz for "black lake", replacing the older Tajik name Siob; Russian: ; Tajik: ) is a 25 km (16 mi) diameter lake within a rather large 52 km (32 mi) impact crater. A large bolide impact created the 100-kilometre (62 mi) diameter crater approximately 35 million years ago during the late Eocene epoch (Priabonian stage). The other three basaltic impact Eugene Merle Shoemaker (April 28, 1928 July 18, 1997) was an American geologist.He co-discovered Comet ShoemakerLevy 9 with his wife Carolyn S. Shoemaker and David H. Levy.This comet hit Jupiter in July 1994: the impact was televised around the world. Under intense pressure (but limited temperature), the crystalline structure of quartz is deformed along planes inside the crystal. An impact structure is a generally circular or craterlike geologic structure of deformed bedrock or sediment produced by impact on a planetary surface, whatever the stage of erosion of the structure. Official name: Karakul Lake: Designated: 18 July 2001: Reference no. These planes, which show up as lines under a microscope, are called planar deformation features (PDFs), or shock lamellae. The Sudbury Basin (/ s d b r i /), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada.It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. In many cases, on Earth, the impact crater has been destroyed by erosion, leaving only the The Chicxulub crater (IPA: [tikulub]) is an impact crater buried underneath the Yucatn Peninsula in Mexico. For eroded or buried craters, the stated diameter typically refers to the best available estimate of the original rim diameter, and may not correspond to The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of South Africa.It is named after the Above a certain threshold size, which varies with planetary gravity, the collapse and modification of the transient cavity is much more extensive, and the resulting structure is called a complex crater.The collapse of the transient cavity is driven by gravity, and involves both the uplift of the central region and the The Late Heavy Bombardment (LHB), or lunar cataclysm, is a hypothesized event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago, at a time corresponding to the Neohadean and Eoarchean eras on Earth. Continued slumping of sediments over the rubble of the crater has helped shape the Chesapeake Bay When large objects impact terrestrial planets such as the Earth, there can be significant physical and These features were caused by the collision of meteors (consisting of large fragments of asteroids) or comets (consisting of ice, dust particles and rocky fragments) with the Earth. The basin is located on the Canadian Shield in the city of Haughton impact crater is located on Devon Island, Nunavut in far Northern Canada. In many cases, on Earth, the impact crater has been destroyed by erosion, leaving only the Description. [1] The impacting object is estimated to have been approximately 2 km (1.2 mi) in diameter. The reserve is located 125 km (78 mi) south west of Alice Springs and contains over a dozen craters, which were formed when a fragmented meteorite hit the Earths surface. The Chesapeake Bay impact crater was formed by a bolide that struck the eastern shore of North America about 35.5 0.3 million years ago, in the late Eocene epoch. These features were caused by the collision of large meteorites or comets with the Earth. An impact event is a collision between astronomical objects causing measurable effects. It is located in the Tajik National Park in the Pamir Mountains in Tajikistan The basin straddles the old provinces of Transvaal and the Orange Free State, and Lake El'gygytgyn (Russian and Chukchi: ) is an impact crater lake located in the Chukotka Autonomous Okrug in northeast Siberia, about 150 km (93 mi) southeast of Chaunskaya Bay.. The basin is located on the Canadian Shield in the city of This large industry, means that as of 2015 about 80,000 workers, or .5% of total employment, was from the coal industry, down from a peak in It might be linked to the EoceneOligocene extinction event. ISBN 978-1-920843-96-0 (pbk.) Outcrops of the Elliot Formation have been found in the northern Eastern Cape, southern Free State, and in the eastern KwaZulu-Natal provinces of South Africa.Outcrops and exposures are also found in Official name: Karakul Lake: Designated: 18 July 2001: Reference no.

For eroded or buried craters, the stated diameter typically refers to the best available estimate of the original rim diameter, and may not correspond to and Ken McNamara (2009) Australia's meteorite craters Welshpool, W. A. : Western Australian Museum, 2nd ed. In contrast, an impact crater is the surface expression of an impact structure. Continued slumping of sediments over the rubble of the crater has helped shape the Chesapeake Bay Haughton impact crater is located on Devon Island, Nunavut in far Northern Canada. A potentially hazardous object (PHO) is a near-Earth object either an asteroid or a comet with an orbit that can make close approaches to the Earth and is large enough to cause significant regional damage in the event of impact. Robert Sinclair Dietz (September 14, 1914 May 19, 1995) was a scientist with the US Coast and Geodetic Survey.Dietz, born in Westfield, New Jersey, was a marine geologist, geophysicist and oceanographer who conducted pioneering research along with Harry Hammond Hess concerning seafloor spreading, published as early as 19601961.While at the Scripps Institution of [citation needed]Henbury is one of five meteorite impact sites in Australia with remaining meteorite fragments and one of the world's best preserved examples of a small crater field. The crater formed 1.849 billion years ago in the Paleoproterozoic era.. The Sudbury Basin (/ s d b r i /), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada.It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. Location: Nenetsia, Russia. The CretaceousPaleogene (KPg) boundary, formerly known as the CretaceousTertiary (KT) boundary, is a geological signature, usually a thin band of rock containing much more iridium than other bands. It is one of the best-preserved "wet-target" impact craters in the world. In contrast, an impact crater is the surface expression of an impact structure. This large industry, means that as of 2015 about 80,000 workers, or .5% of total employment, was from the coal industry, down from a peak in Meteor Crater, or Barringer Crater, is a meteorite impact crater about 37 mi (60 km) east of Flagstaff and 18 mi (29 km) west of Winslow in the desert of northern Arizona, United States.The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Caon Diablo. Lake El'gygytgyn (Russian and Chukchi: ) is an impact crater lake located in the Chukotka Autonomous Okrug in northeast Siberia, about 150 km (93 mi) southeast of Chaunskaya Bay.. The lake is of particular interest to scientists because it has never been covered by glaciers. Its center is offshore near the community of Chicxulub, after which it is named.It was formed slightly over 66 million years ago when a large asteroid, about ten kilometers (six miles) in diameter, struck Earth.The crater is estimated to be 180 kilometers The crater, which has since been eroded away, was around 160300 km (100200 mi) across when it was formed. 1082: Karakul, Qarokul (Kyrgyz for "black lake", replacing the older Tajik name Siob; Russian: ; Tajik: ) is a 25 km (16 mi) diameter lake within a rather large 52 km (32 mi) impact crater. Description. The Late Heavy Bombardment (LHB), or lunar cataclysm, is a hypothesized event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago, at a time corresponding to the Neohadean and Eoarchean eras on Earth. The KPg boundary marks the end of the Cretaceous Period, the last period of the Mesozoic Era, and marks the beginning of the Paleogene Period, the first period of the A potentially hazardous object (PHO) is a near-Earth object either an asteroid or a comet with an orbit that can make close approaches to the Earth and is large enough to cause significant regional damage in the event of impact. Confirmed impact craters listed by size and age. The Popigai crater (or astrobleme) in Siberia, Russia, is tied with the Manicouagan Crater as the fourth largest verified impact crater on Earth. South Africa produces in excess of 255 million tonnes of coal (2011 estimate) and consumes almost three-quarters of that domestically. The word "Elgygytgyn" means "white lake" in the Chukchi language.. It is one of the best-preserved "wet-target" impact craters in the world.
