Fig. 3: Fluid evacuation features related to Late Cenozoic intraplate volcanism in SW Eurasia Basin.

Enlarged selected portions of seismic data along NPD-1204-402 (Fig. 2 profile 1). a Deformation within basement and sedimentary structures, including the identified Mound-A and the Tayrona Vent, as well as Body-A due to sill intrusions and hydrothermal vent complexes associated to the VEHAI. b, c Mound-A and Tayrona Vent seismic morphologies. d Seismic chimney complex accompanied by velocity push-down effects from basement levels reaching the seafloor and aligned to seabed like-hill features. Shift in seismic facies is indicated by arrow position (See text). See also S3-5 for more details.
