Orocline

Examples

• The Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes mountains at about 18° S. At this point the orientation of the Andes turns from Northwest in Peru to South in Chile and Argentina. The Andean segment north and south of the orocline have been rotated 15° to 20° counter clockwise and clockwise respectively. The orocline area overlaps with the area of maximum width of the Altiplano Plateau according to Isacks the orocline is related to crustal shortening. The specific point at 18° S where the coastline bends is known as the Arica Elbow.
• The Maipo Orocline or Maipo Transition Zone is an orocline located between 30° S and 38°S in the Andes with a break in trend at 33° S.
• The Arauco Orocline a subtle orocline located at 37° S in south-central Chile. It marks a seaward-convex bend in the Andes.
• Bothnian oroclines in the Svecofennian Domain in Finland and Sweden.
• Inari orocline including the Lapland Granulite Belt in Finland, Norway and Russia.
• Cantabrian Orocline, Spain
