The island of Tristan da Cunha is the largest of a group of three islands, the others being Nightingale and Inaccessible. It has a north-south length of 11.27 km and an area of 98 km². The remote Gough Island is located about 400 km south-east of Tristan da Cunha.

Tristan da Cunha Island comprises a continuous series of alkaline lavas ranging in composition from ankaramitic basanite through phonotephrite and tephrophonolite to phonolite. Moderately porphyritic basanite is the dominant rock type on the island.
