Extract

The special interest of South Georgia depends on its evidence regarding the geology of the part of the Southern Ocean which lies south of the South Atlantic. According to Professor Suess, the island is an extension of the Andes, which, at the southern end of South America, turn eastward, and by a great horse-shoe-shaped curve pass through South Georgia to the South Orkneys and Graham Land.

The geology of South Georgia is but little known. Thürach † described the island as consisting of metamorphic rocks, ranging from granular gneiss to clay-slate, and of diabase tuff.
