Sudbury Basin is the third-largest crater on Earth, after the 300 km (190 mi) Vredefort impact structure in South Africa, and the 180 km (110 mi) Chicxulub crater under Yucatán, Mexico. Geochemical evidence suggests that the impactor was likely a chondrite asteroid or a comet with a chondritic component.
The Sudbury Impact Structure of Ontario is a world-class locality for pentlandite and other metallic sulfides. The massive sulfide rock shown above is from Sudbury. The Sudbury Complex (Sudbury Basin) in southeastern Canada has intrigued geologists for decades, and not just due to the tremendous economic value of the area’s mineral deposits.
It is located near the much larger Sudbury meteorite crater but they are not related. Lake Wanapitei seen from space, upper right of the image. The crater is 5.2 mi (8.4 km) in diameter and the age is estimated to be 37.2 ± 1.2 million years, placing it in the Eocene. [1] It was evident by the mid-1970s that Wanapitei Lake was an impact crater.

A man planning a camping trip using Google Maps ran across a uniquely curved spherical pit in Quebec and started asking questions. The site is now considered a “strong contender” to be a ...
Sudbury Basin is the third-largest crater on Earth, after the 300 km (190 mi) Vredefort impact structure in South Africa, and the 150 km (93 mi) Chicxulub crater under Yucatán, Mexico. [10] The Sudbury Igneous Complex is an impact melt that formed from this impact and the high pressures and temperatures melted the surrounding rock. [11]
Ramsey Lake (French: Lac Ramsey) is a lake in Sudbury, Ontario, located near the city's downtown core. Until 2001, Ramsey Lake was listed by the Guinness Book of World Records as the world's largest lake located entirely within the boundaries of a single city, [citation needed] but when the Regional Municipality of Sudbury was amalgamated into the current city of Greater Sudbury, Ramsey Lake ...
