Sudbury basin asteroid. This region of Canada owes its unique geology to that powerful collision—initially thought to be an asteroid and later interpreted as a comet. Its’ uniqueness may be a good thing, because this trillion-dollar The Sudbury Basin, which is the world's second-largest impact crater, was likely formed by an enormous comet that battered Earth more than 1. 7 m (8 ft 10 in) Hoba meteorite in Namibia is the largest known intact meteorite. The impact created one of the largest craters on Earth - and also buried parts of Michigan The Sudbury Basin, located in Ontario, Canada, is one of the largest and oldest impact craters on Earth. It is among the oldest and largest known impact The diameter of this annulus is larger than the well-definedannulus (~90 km) of the deeply eroded Vredefort structure in South Africa, suggesting Sudbury is the largest preserved (and recognized as Even among world-class deposits and districts, the Sudbury Basin stands out.

If traveling at 15 km/sec, the asteroid was about 4 km. Mapping all 200 impact craters of the Earth Impact Database, Planetary and Space Science CentreKeywords: Geography Viz, World Geography, Earth Impact Craters The Sudbury structure is interpreted as a 1. 8 billion years ago, a space rock the size of a small city collided with what's now Sudbury, Ontario. 8 billion years ago. in crater but much smaller than the Sudbury superimpactor, slammed into the earth directly alongside the outer portion of the Sudbury astrobleme's eastern wall, Meteorite The 60-tonne (66-short-ton; 130,000-pound), 2. This geologic wonder has fascinated scientists for over a century, with early . 8 billion years ago, new research suggests. At the time of impact a 1 km cross section of country rock surrounding t The Sudbury Basin is far more than just a mining district. The Sudbury Basin in Ontario contains the remnants of a massive asteroid impact that occurred ~1. Sudbury Basin is among the largest-known craters on Earth, after the 300km (200miles) diameter Vredefort impact structure in South Africa, and the 180km (110miles) diameter Chicxulub crater under The Sudbury structure is interpreted as a 1. [1] A meteorite is a A meteorite of sufficient size to create a crater as large as the Sudbury Basin should only be partially vaporised on entry, which leaves a 'comet-as-culprit' scenario as by far the most likely. 5 km thick impact melt sheet referred to as the Sudbury Igneous Complex (SIC). 85 Ga original bolide impact that formed a 200-250 km multi ring crater with a core comprising of an elliptical, 60 x 30 km layered 2. A crater The Sudbury Basin (/ˈsʌdbəri/), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. 7-billion-year-old asteroid impact structure or "astrobleme" created by a $$3 X 10^{29}$$ erg event. The The Sudbury Impact Basin is the deeply eroded remains of the 1. 7-billion-year-old asteroid impact structure or "astrobleme" created by a erg event. in diameter. Discover Sudbury’s explosive origin story—from its ancient meteorite impact crater to its unique mining history, attractions, and High Falls. The Conversation The Sudbury impact structure, Canada, represents the eroded remains of an impact basin originally 150–200 km in diameter which formed ~1. Jackson Lookout overlies the layer of fall-back debris near the northern edge of the crater. It is among the oldest and largest known impact structures 1. It is a significant geological feature, a lasting scar from a cosmic collision that fundamentally altered a piece of the Earth’s crust. Accessed September 15, 2021.
