Ilhas oceânicas da Trindade e Fernando de Noronha, Brasil: Uma visão da Geologia Ambiental

This study highlights significant geological and environmental changes affecting the Brazilian Atlantic Islands, specifically Fernando de Noronha and Trindade. The research reveals that these islands, composed of alkaline ultrabasic to intermediate rocks and Pleistocene-Holocene sedimentary deposits, have undergone substantial erosion due to deforestation and coastal engineering projects, particularly in Fernando de Noronha's Santo Antonio port. In Trindade, erosion is primarily attributed to deforestation caused by the introduction of livestock in the 18th century. The study also identifies sea-level variations and wave climate changes as critical factors exacerbating coastal erosion. By analyzing paleodunes, beaches, alluvial deposits, algal reefs, and coral reefs, the research provides a comprehensive understanding of the geological and oceanographic processes shaping these UNESCO World Heritage Sites.
