1, p. 20-21. The city has eight urban areas, including the old city of Sudbury, Azilda and Capreol. Address: 4472 Long Lake Rd, Sudbury, ON P3G 1K4 – Approximately 10 min from Sudbury and 4 hrs north of Toronto. Associated Press: "Ontario crater debris found in Minn.", Pye, E.G., Naldrett, A.J. Retrieved from " https://commons.wikimedia.org/w/index. Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites. Debris from the impact was scattered over an area of 1,600,000 km2 (620,000 sq mi) thrown more than 800 km (500 mi); rock fragments ejected by the impact have been found as far away as Minnesota.[4]. Its present size is believed to be a smaller portion of a 130 km (81 mi) round crater that the bolide originally created. Accordingly, the region primarily supplies products for consumption within Northern Ontario, and is not a major food exporter. The median age of the people of Sudbury is 41.1 years, which is higher than the national average of 39 years. Schulz, J.W. The Sudbury Basin (/ˈsʌdbəri/), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. All I can find Locally known as the City of Lakes, Greater Sudbury contains 330 lakes, more than any other municipality in Canada. This feature (and the similar-sized crater to its left) is overprinted by many other craters, meaning it is an extremely old feature that has collected other impacts over the eons. XTERRA Conquer the Crater: a race like no other! Geologists reached consensus by about 1970 that the Sudbury basin was formed by a meteorite impact[citation needed]. • The original crater is guessed to be about 250 km in diameter. Satellite Image. If uncertainties regarding its age are resolved, then the largest in the last 10 million years would be the 52-kilometre (32 mi) Karakul crater which is listed in EID with an age of less than 5 Ma, or the Pliocene. The analogy between the Sudbury Structure and lunar maria, though petrologically wrong, is valid to the extent that both classes of structure were initially formed by impact. GeoNames. Lake Wanapitei, at the northeastern edge of the Sudbury Basin, fills another impact crater with a diameter of 8 km, and a age of 37 million yeras. Samarium-neodymium isotopic data on whole rocks and minerals of the Sudbury Complex in Canada gave an igneous crystallization age of 1840 ± 21 x 106 years. It is the second-largest verified impact crater on Earth, as well as one of the oldest. ~Sudbury Basin Crater~ By: Savannah Kai Harris Thank you! The Vredefort crater's age is about two billion (10 9) years ago, which puts it in the Palaeoproterozoic era. La città di Greater Sudbury… A close-up of the brecciated iron formation. Age: 35 million years. Models suggest that for such a large impact, debris was most likely scattered globally,[5] but has since been eroded away. Source: wikimedia.org. This view of Saturn's moon Rhea includes two large and ancient impact basins and a more recent, bright ray crater. The Basin is one of the world's largest suppliers of nickel and copper ores. Scientists explained the causes of its formation. (1984), List of possible impact structures on Earth, Planetary and Space Science Centre University of New Brunswick Fredericton, "Discovery of the Sudbury Nickel Deposits", "Structural characteristics of the Sudbury impact structure, Canada: Impact-induced versus orogenic deformation-A review", "On the track of the elusive Sudbury impact: geochemical evidence for a chondrite or comet bolide", "A Comet Did It! Il cratere di Sudbury o bacino di Sudbury, più noto col suo nome inglese di Sudbury Basin, è uno dei più grandi crateri di origine meteoritica finora scoperti sulla Terra e anche uno dei più antichi. 9883724. [citation needed], Because considerable erosion has occurred since the Sudbury event, an estimated 6 km (3.7 mi) in the North Range, it is difficult to directly constrain the actual size of the diameter of the original transient cavity, or the final rim diameter.[6]. • Original crater altered by subsequent geologic processes From 1945, Sudbury’s population grew at a rate of 10% each year until tripling at nearly 7500 in 1960. The basin is located on the Canadian Shield in the city of Greater Sudbury, Ontario. [citation needed], NASA used the site to train the Apollo astronauts in recognizing rocks formed as the result of a very large impact, such as breccias. Stanley, J.R. MOrrow, G.J. Pufahl P.K., E.E. Muehlberger. The mystery of the Sudbury Basin solved: The second largest crater on Earth was caused by a massive COMET hitting the planet 1.8 billion years ago Ontario crater … Physical features Size - 32 km wide ( 104,986..877 feet), 15 km deep (49,212.5984 feet) Unfair and outdated reputation as an environmental wasteland Lots of tourism with bilingual tours LOCATION Age and Impact This crater The initial epsilon neodymium values for 15 whole rocks are similar to those for average upper continental crust, falling on the crustal trend of neodymium isotopic evolution as defined by shales. The Sudbury Igneous Complex (SIC) represents the ponded melt sheet. (2010) Stratigraphy of Sudbury "impactite" near Gunflint Lake, NE Minnesota. Geology, v. 35, p. 827-830. The Sudbury Basin is referred to locally as "The Valley". Stay current with news, sports, entertainment, classifieds, events and more. [17], As a result of these metal deposits, the Sudbury area is one of the world's major mining communities, and has fathered Vale Inco and Falconbridge Xstrata. Fralick, P.W. ago. (1967) Sudbury Structure, Ontario: Some Petrographic Evidence for Origin by Meteor Impact. Ore deposits associated with the impact structure can be subdivided into contact, footwall and offset types, and represent the end products of … The basin is on the Canadian Shield in the city of Greater Sudbury, Ontario. The urban core of the former city of Sudbury lies on the southern outskirts of the basin. Nahimutang ni sa kondado sa Sudbury ug lalawigan sa Ontario, sa habagatan-sidlakang bahin sa nasod, 400 km sa kasadpan sa Ottawa ang ulohan sa nasod. [2] Den är den tredje största kända nedslagskratern på jorden. Journal of Geology, Vol 72, p. 412-434, doi:10.1086/626999. It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. Vallini, N.J. McNaughton, D.W. Navis, S.A. Kissin, P.W. Petrological, geochemical, and structural evidence supports genesis of the Sudbury Structure by a meteorite impact. The former municipalities of Rayside-Balfour, Valley East and Capreol lie within the Sudbury Basin, which is referred to locally as "The Valley". Sudbury, officially Greater Sudbury, in full City of Greater Sudbury, city, seat of Sudbury district, southeastern Ontario, Canada.It is situated on the western shore of Ramsey Lake, about 40 miles (65 km) north of Georgian Bay of Lake Huron.. The remainder live in … Considered to be one of the best-preserved “wet-target” impact craters in the world, the Chesapeake Bay Crater is … Den ligger i countyt Sudbury och provinsen Ontario, i den sydöstra delen av landet, 400 km väster om huvudstaden Ottawa.Toppen på Sudbury Impact Crater är 322 meter över havet, [b] eller 21 meter över den omgivande terrängen [c]. Hiatt, C.R. [10] In 2014, analysis of the concentration and distribution of siderophile elements as well as the size of the area where the impact melted the rock indicated that a comet rather than an asteroid most likely caused the crater.
