The small island of Trindade lies more than halfway between Brazil and the Mid-Atlantic Ridge at the eastern end of the Vitória-Trindade Ridge, an E-W-trending chain of submarine volcanoes and guyots extending about 1,100 km from the continental shelf off the Brazilian coast. It is a dissected volcanic island with numerous phonolitic lava domes and steep-sided volcanic plugs. The youngest volcanism, at Vulcao de Paredao on the SE tip of the island, constructed a pyroclastic cone with lava flows (Almeida, 1961). Remnants of the crater of the cinder cone are still preserved. Lava flows traveled from the cone to the N, where they form an irregular shoreline and offshore islands. Smaller centers of the latest volcanic stage are found in the Morro Vermelho area in the south-central part of the island.
