The city of Sudbury is located to the south-east of the SIC. Formation of the original crater The Sudbury Structure is situated within a unique Geotectonic setting in northeastern Ontario, being sandwiched between: the Archean-age (>2.5 billion-year-old) Superior Geologic or Structural Province, situated to west and north of the structure, and;

Sudbury Basin Crater 10 Biggest Impact Craters on Earth Geology
Abstract— Orogenic deformation, both preceding and following the impact event at Sudbury, strongly hinders a straightforward assessment of impact‐induced geological processes that generated the Sudbury impact structure. Central to understanding these processes is the state of strain of the Sudbury Igneous Complex, the solidified impact melt sheet, its underlying target rocks, overlying.
SUDBURY IMPACT STRUCTURE Crater Explorer
The Sudbury structure is a large (D ~200 km, 1850 Ma), deformed and eroded impact crater, whose central region was occupied by melt. An eight-year multidisciplinary study by Stoffler et al. (1994) concluded that the impact excavated deep into the crust, almost to the mantle (~30 km), before collapse and rebound.

Definition The Sudbury impact structure, Canada, represents the eroded remains of an impact basin originally 150-200 km in diameter which formed ~1.85 Ga ago. It contains world-class ore deposits, associated with the Sudbury Igneous Complex, which represents the differentiated original impact melt sheet.

The Sudbury Basin ( / ˈsʌdbəri / ), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. [1] The crater was formed 1.849 billion years ago in the Paleoproterozoic era. [2]

SHATTERCONES This 18 cm shattercone was found just outside of the Sudbury Igneous Complex (SIC). The discovery of shatter cones confirmed that a large meteorite impact caused the formation of the Sudbury Igneous Complex (Gibson, Spray 1998). After 1.85 Billion years the striations on the shatter cone illustrated above are still recognizable.
Sudbury Impact Structure
The present-day remnant of the Sudbury Meteorite Crater is composed by a surrounding brecciated footwall rocks of both the Superior and southern Structural Geologic Provinces extending up to 100 km away from the position of the Sudbury Igneous Complex (SIC), the SIC itself and rocks of the Whitewater Group (melt breccia, suevite, and reworked suevite) in the Sudbury Basin within the SIC.

First, the Sudbury date pattern can be correlated with fractures in the central peak crater Haldane (36 km in diameter). This comparison indicates an initial Sudbury diameter of between 100 and 140 km but requires loss of a central peak complex for which there is little evidence.
