Sub-Antarctic islands have a diversity of origins in detail but most are volcanic and very young suggesting that they are short-lived and
that the distribution would have been very different a few million years ago. Ihey contrast with the common tourist brochure concept of
oceanic islands. As the Antarctic Plate is virtually static, the islands seldom show signs of association with long-lived linear island chains and
most thus stand alone. Longer-lived islands are either on submarine plateaux or are continental remnants of the dispersion of Gondwana.
The islands are classified in relation to raised sea-floor, transform fault, triple junction, subduction zone, submarine plateau, submerged
continent or continental. Many are difficult of access and poorly known geologically. Their geological history controls their many other
roles such as sites as observatories, or for study of colonisation, evolution and speciation rates.
