The Galapagos Spreading Centre: Lithospheric Cooling and Hydrothermal Circulation [PDF]
Geophysical Journal International, 1974 Summary The spatial pattern of cooling near a spreading ridge crest was investigated with a suite of 71 precisely-navigated heat-flow stations on the Galapagos spreading centre, East Pacific, near 86"W longitude. Stations are on crust less than 1.0 My old on which bathymetry and sediment distribution are well known.

Geofluids, 2019 Aiming at investigating the hydrothermal circulation along the eastern flank of the Vulture volcano, along the outermost edge of the southern Apennine fold-and-thrust belt (ftb), we studied the fossil hydrothermal alteration that mineralized a ...

Geochemistry Geophysics Geosystems, 2019 The Endeavour segment of the Juan de Fuca Ridge is one of the most active and long‐lived hydrothermal areas of the mid‐ocean ridge system. However, the permeability structure that gives rise to long‐term venting at well‐established fields, such as the ...

Geological constraints for a conceptual evolutionary model of the slope deformations affecting Mt. Nuovo at Ischia (Italy) [PDF]
, 2015 ischia island was the scenario of several Holocene slope in- stability events occurred at different scales, from shallow mass movements, triggered by meteo-climatic forcing, up to massive rock slope failures such as large debris avalanches these last ...

Sediment mixing in the tropical Pacific and radiolarian stratigraphy
Geochemistry, Geophysics, Geosystems, 2012 The reworking of older radiolarian microfossils into near‐surface sediments of the tropical Pacific has long been the source of confusion for the development of radiolarian stratigraphy and of puzzlement over the mechanism(s) that could effect such ...

Topographic and Faults Control of Hydrothermal Circulation Along Dormant Faults in an Orogen
Geochemistry Geophysics Geosystems, 2018 Hydrothermal systems involving dormant faults within orogenic belts are rarely targeted for geothermal exploration, partly because of the complexity of the 3‐D topography, the unknown permeability of the fault zones and the basement lithology, and the ...

The vertical distribution of iron stable isotopes in the North Atlantic near Bermuda [PDF]
, 2012 Seawater dissolved iron isotope ratios (δ^(56)Fe) have been measured in the North Atlantic near Bermuda. In a full-depth profile, seawater dissolved δ^(56)Fe is isotopically heavy compared to crustal values throughout the water column (δ^(56)Fe_(IRMM-014)

Journal of Geophysical Research: Solid Earth, 2018 Long‐lived hydrothermal circulation is now well documented along slow and ultraslow spreading mid‐ocean ridges, even though these settings only receive a moderate and intermittent supply of magma.
