Approximate Form and Extent of Outcrop of Carbonate Rocks
WorldPhysical EnvironmentExtent of carbonate rocks or predominantly carbonate sequences
USGSA map showing the approximate form and extent of outcrop of carbonate rocks worldwide, highlighted in green.
The outcrops of carbonate rocks are scattered across various regions. In North America, notable areas include the southeastern United States and parts of Mexico. The Caribbean also has some carbonate rock outcrops. In South America, small outcrops are present in Brazil. Africa has outcrops in northwestern and southern regions, including Morocco, Algeria, and South Africa. Europe shows significant outcrops in central and southern areas, particularly in countries like Spain, Italy, and Austria. Russia has some outcrops, while Asia has smaller areas of outcrops in countries like Myanmar, Vietnam, Sri Lanka, and Japan. In Australia, outcrops are found in the southern part of the country.
