Background
The small island of Trindade lies at the eastern end of an E-W-trending chain of submarine volcanoes and guyots extending about 1100 km from the continental shelf off the Brazilian coast. The island lies more than halfway between Brazil and the Mid-Atlantic Ridge near the eastern end of the submarine Vitória-Trindade Ridge. Trindade 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 that are no older than Holocene (Almeida, 1961). Remnants of the crater of the 200-m-high cinder cone are still preserved. Lava flows traveled from the cone to the north, where they form an irregular shoreline and offshore islands. Smaller volcanic centers of the latest volcanic stage are found in the Morro Vermelho area in the south-central part of the island.---
