Abstract
The Bauer Deep, in the south-eastern equatorial Pacific, is the only deep ocean basin so far known to be characterised by metalliferous sediments throughout the depositional column. The basin was formed when the eastern Pacific spreading centre jumped from the now fossil Galapagos Rise to the newly formed East Pacific Rise. The distinctly bimodal distribution of heat flow in the Bauer Deep indicates that precipitation from hydrothermal fluids emanating from the oceanic crust may be the mechanism for metallogenesis in the Bauer Deep. The hydrothermal circulation may have been initiated by the emplacement, approximately ∼ 6 Myr BP, of a heat source associated with the ridge jump into that vicinity.
