The Sudbury Basin (/ ˈ s ʌ d b ə r i /), 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 structure on Earth , as well as one of the oldest. [ 1 ]
Sediment erosion and deposition dynamics in estuarine region, consequently the formation and growth of mouth bars, are affected by several natural and artificial factors. . Human activities, such as reservoir construction, large-scale reclamation and embankment construction completely disturb the hydrodynamic balance of the system and permanently interfere with the morphology of mouth bars.
The Ring of Fire is a vast, mineral-rich region located in the remote James Bay Lowlands of Northern Ontario, Canada.Spanning approximately 5,000 square kilometres (1,900 sq mi), the area is rich in chromite, nickel, copper, platinum group elements, gold, zinc, and other valuable minerals.
The geology of Ontario is the study of rock formations in the most populated province in Canada- it is home to some of the oldest rock on Earth. The geology in Ontario consists of ancient Precambrian igneous and metamorphic rock which sits under younger, sedimentary rocks and soils. Around 61% of Ontario is covered by the Canadian Shield. The ...

The environment of deposition for these sediments has changed, varying spatially and temporally. When the ocean level was high shallow marine deposits occurred; when they were low fluvial and deltaic deposits form the majority of mass. [26] From the Triassic until the early Jurassic, faulting localized as extension faulting and wrench faulting.
The Gunflint Range is an iron ore deposit in northern Minnesota in the United States and Northwestern Ontario, Canada. The range extends from the extreme northern portion of Cook County, Minnesota into the Thunder Bay District, Ontario. The Gunflint Iron Formation is a continuation of the Mesabi Range to the southwest.
The Abitibi greenstone belt is a 2,800-to-2,600-million-year-old greenstone belt that spans across the Ontario–Quebec border in Canada. [1] It is mostly made of volcanic rocks, but also includes ultramafic rocks, mafic intrusions, granitoid rocks, and early and middle Precambrian sediments.
