Abstract

The Vitória-Trindade Ridge, situated in the central South Atlantic Ocean, is the longest aseismic ridge. The ridge comprises alkaline volcanic formations, including seamounts such as Davis, Colúmbia, Congress banks, Jaseur, Montague, and Vitória. The VTR resulted from a mantle plume, making it structurally complex. A study was conducted to investigate the structure of the VTR using gravity anomalies and bathymetric data. The study revealed the 3D structure of seamounts in terms of their density, depth, and volume. The results showed that the volume of seamounts with depth of VTR ranges from 10 to 14 km. Additionally, the uneven distribution of density contrast indicates the complex structure of the VTR region.
