Reports published in the late 1960s described geological features that were said to be distinctive of meteorite impact, including shatter cones and shock-deformed quartz crystals in the underlying rock. Geologists reached consensus by about 1970 that the Sudbury basin was formed by a meteorite impact.
Why is the Sudbury Basin Oval?
The elliptical appearance is due to post-impact tectonism, with shortening to the northwest. A weak fracture halo is developed to the north, exterior to the Igneous Complex. The Sudbury Igneous Complex has associated major nickel and copper ore-bodies, which are currently mined.
How was the Sudbury Basin formed?
The Sudbury Basin, which is the world’s second-largest impact crater, was likely formed by an enormous comet that battered Earth more than 1.8 billion years ago, new research suggests.
Why is the area around Sudbury so rocky?
This region of Canada owes its unique geology to that powerful collision—initially thought to be an asteroid and later interpreted as a comet. The collision punctured Earth’s crust, allowing material from the mantle to well up from below and fill the basin with melted rock.
Was Sudbury hit by a meteor?
A meteorite believed to be 10 to 16 kilometres in diameter hurtles from space striking the area now known as Sudbury, Ontario (700 kilometres away)! An impact crater 250 kilometres wide is created, which forms the second biggest known crater on our planet (Figure 2).
Is Sudbury Superstack still standing?
A fixture of the city since the early 70s and the second tallest chimney in the world at 1,205 feet, the Superstack has been a part of the Greater Sudbury skyline for almost 50 years.
What’s the biggest crater on Earth?
the Vredefort crater
At roughly 62 miles (100 kilometers) in diameter, the Vredefort crater, located near the present-day city of Johannesburg, South Africa, is the largest and oldest-known impact crater on the planet.
Why are the rocks in Sudbury black?
Many of the rocks at Dynamic Earth, as elsewhere in the Greater Sudbury area, are a distinctive black colour. Is this natural? Greater Sudbury’s rocks are not naturally black – rather, rock surfaces were stained black by early mining practices. Early smelter emissions contained sulphur dioxide and metal particulate.
Where is the biggest meteor crater on Earth?
South Africa
About 2 billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa, and forming the Vredefort crater – the biggest and oldest terrestrial impact crater known so far.
How large is the Sudbury Basin?
The Sudbury Basin is the second largest known impact crater on Earth — 62 kilometres long, 30 kilometres wide and 15 kilometres deep. Joe Petrus is a researcher at Laurentian University in Sudbury.
How deep is the Sudbury Basin?
15 km
The full extent of the Sudbury Basin is 62 km (39 mi) long, 30 km (19 mi) wide and 15 km (9.3 mi) deep, although the modern ground surface is much shallower.
Why do people like to live in Sudbury?
There are many great reasons to consider moving to Sudbury. It is an ideal place to live if you love the outdoors and nature. It is a diverse community with a strong economy along with a great education and healthcare system. It’s an ideal city to raise a family.
What’s Sudbury famous for?
rock mining capital
With nine operating mines, two mills, two smelters, and a nickel refinery, Sudbury is arguably the hard rock mining capital of the world. Sudbury is home to a major geological structure in Ontario, Canada called the Sudbury Basin which is the third-largest crater on Earth, as well as one of the oldest.
Is there a volcano in Sudbury?
Sudbury Volcano | John Seach
Sudbury is the erosional remnant of an impact basin 250 km in diameter. Sudbury igneous complex represents solidified impact body melt.
What is the Sudbury incident?
“Information provided was that two individuals had been in a verbal argument where a man made racial slurs towards another customer resulting in a physical altercation between the two individuals outside of the store,” police said in a news release. “The investigation into the incident is ongoing.”
When was the last big meteor hit?
The 2013 Chelyabinsk meteor was estimated to be about 20 m in diameter with an airburst of around 500 kilotons, an explosion 30 times the Hiroshima bomb impact. Much larger objects may impact the solid earth and create a crater.
Is the Superstack gone?
In 2018, Vale announced that the stack would be decommissioned and dismantled beginning in 2020. Two new, smaller stacks were constructed under the company’s Clean Atmospheric Emissions Reduction Project.

Why did Sudbury Downs close?
After months of negotiations, the racetrack said it was unable to reach a profitable deal.
Where did the meteor hit that killed the dinosaurs?
The Chicxulub crater
The Chicxulub crater (IPA: [tʃikʃuˈlub]) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore near the community of Chicxulub, after which it is named.
Will an asteroid hit Earth 2022?
It has since been confirmed that 2022 AE1 will not impact Earth and has been removed from ESA’s risk list. So, what’s the story behind the excitement, and how can we trust this seemingly ‘meandering’ impact risk?
