South Georgia Islands
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. Surface expressions of the plate boundary are found north of the islands suggesting a long-term presence of the transform fault there. Yet seismic studies have identified strain and thrusting south of the islands indicating the possible shift of the transform fault to an area south of the island. 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.

Famous quotes containing the words south, georgia and/or islands:
“Whenever I’m asked why Southern writers particularly have a penchant for writing about freaks, I say it is because we are still able to recognize one. To be able to recognize a freak, you have to have some conception of the whole man, and in the South the general conception of man is still, in the main, theological.”
—Flannery O’Connor (1925–1964)
“Georgia, Georgia, no peace I find, just an old sweet song keeps Georgia on my mind.”
—Stuart Gorrell (d. 1963)
“we are so many
and many within themselves
travel to far islands but no one
asks for their story....”
—Denise Levertov (b. 1923)
