Scotia Plate

It forms the western portion of the Scotia Plate.

Bounded by subducting, spreading and transform ridges, the Scotia plate lies in a particular setting.

This volcanic group lies south of the Magallanes-Fagnano Fault, on the Scotia Plate.

The relative motion between the Scotia plate and the Antarctic plate on the western boundary is roughly 13 mm/yr.

The southerly side is a complex boundary with the Antarctic Plate and the Scotia Plate.

In the extreme south a major transform fault separates Tierra del Fuego from the small Scotia Plate.

The fault marks a transform boundary between the Scotia Plate and the South American Plate, cutting across continental crust.

It is hemmed in the active tectonic plate (linked to the Magallanes-Fagnano fault) boundary between the South American and Scotia plates.

The Scotia Plate, named after the sea which overlies it, is a tectonic plate on the edge of the South Atlantic and Antarctic Ocean.

The Northern edge of the Scotia plate is bounded by the South American plate forming the North Scotia ridge.

Spreading began to generate two new oceanic plates between South American and Antarctica, the so-called Magellan and Central Scotia plates.

A change in motion between the South American plate and the Antarctic plate would have severe effects, causing seafloor spreading and the formation of the Scotia plate.

The East Scotia Ridge is a suboceanic volcanic ridge in the Southern Ocean, on the eastern extremity of the Scotia Plate.

It has also been suggested that the plate may have broken off from the Scotia plate forming a new independent South Georgia microplate yet there is little evidence to make this conclusion.

The eventual death of the Mid-Scotia ridge led the Magellan and Central Scotia plates to join forming the Scotia plate as seen today.

This part of the strait lies on the elongated Magallanes-Fagnano Fault, which marks a plate boundary between the South American Plate and the Scotia Plate.

Highly disputed, tectonisists have been unable to determine whether the South Georgian Islands are part of the Scotia plate or have been recently amalgamated to the South American plate.

Shackleton Fracture Zone (abbreviated as SFZ) is an undersea fracture zone and fault located on Drake Passage that separates the Scotia Plate from the Antarctic Plate.

Other notable plates include the Arabian Plate, the Caribbean Plate, the Nazca Plate off the west coast of South America and the Scotia Plate in the southern Atlantic Ocean.

The timing of the formation of the Scotia plate and opening of the Drake Passage has long been the subject of much debate due to its important implications for changes in ocean currents and shifts in paleo-climate.

The South Sandwich Plate or microplate is a tectonic plate bounded by the subducting South American Plate to the east, the Antarctic Plate to the south and the Scotia plate to the west.

Thinner and denser than the continental Antarctic and South American plates, the growing Magellan and Central Scotia plates formed a deep and increasingly wide passage, the Drake Passage between South America and Antarctica.

The Antarctic Plate has a boundary with the Nazca Plate, the South American Plate, the African Plate, the Indo-Australian Plate, the Scotia Plate and a divergent boundary with the Pacific Plate forming the Pacific-Antarctic Ridge.
