Interpretation of High-Resolution Remote Sensing Data for Plio-Pleistocene Tectonic Structures Studies in the Trindade Island Volcanic Building, South Atlantic Ocean, Brazil
Trindade Island (20°31′0’ S and 29°19′0 W) is a large alkaline volcanic edifice and is the only emerging part of the Vitória-Trindade ridge, 1140 km from the Brazilian offshore, whose summit is around 600 meters high. The lineament orientation pattern of Plio-Pleistocene dykes and fractur...
