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 Igneous Complex is a 1,844 million year-old impact melt sheet in Greater Sudbury, Northern Ontario, Canada. It is part of the Sudbury Basin impact structure, and is classified as a lopolith.
Sudbury Basin, 130 km (81 mi) Chicxulub crater, 150 km (93 mi) Popigai impact structure, 100 km (62 mi) Manicouagan impact structure, 100 km (62 mi) Acraman crater, 85 to 90 km (53 to 56 mi) Charlevoix impact structure, 54 km (34 mi) Nördlinger Ries, 24 km (15 mi)
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]
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
Two of the largest known impact events on Earth occurred during the Orosirian. Early in the period, 2023 Mya, a large asteroid collision created the Vredefort impact structure. The event that created the Sudbury Basin structure occurred near the end of the period, 1850 Mya.
The Sudbury Basin structure is located in Greater Sudbury [10]: 1891 at the erosional boundary between the Archean Superior province and the overlying sequence of early Proterozoic continental margin deposits.
The Sudbury Basin was caused by an impacting body over 9.7 km (6 mi) in diameter. [34] [35] This basin is famous for its deposits of nickel, copper, and platinum group elements. An impact was involved in making the Carswell structure in Saskatchewan, Canada; it contains uranium deposits. [36] [37] [38] Hydrocarbons are common around impact ...
