Permeability within basaltic oceanic crust

AT Fisher - Reviews of Geophysics, 1998 - Wiley Online Library
Water‐rock interactions within the seafloor are responsible for significant energy and solute
fluxes between basaltic oceanic crust and the overlying ocean. Permeability is the primary …

Magmatism at mid-ocean ridges: Constraints from volcanological and geochemical investigations

MR Perfit, WW Chadwick - Geophysical Monograph-American …, 1998 - books.google.com

Linkages between faulting, volcanism, hydrothermal activity and segmentation on fast spreading centers

KC Macdonald - Geophysical Monograph Series, 1998 - ui.adsabs.harvard.edu
Systematic variations occur along the crests of intermediate-to fast-spreading ridges which
suggest linkages between volcanism, faulting, hydrothermal activity and magma supply …

Seismic structure and indicators of magma budget along the southern East Pacific Rise

EEE Hooft, RS Detrick, GM Kent - Journal of Geophysical …, 1997 - Wiley Online Library

Internal structure of oceanic lithosphere: A perspective from tectonic windows

JA Karson - Geophysical Monograph Series, 1998 - ui.adsabs.harvard.edu
Major faulted escarpments on the seafloor provide" tectonic windows" into oceanic crust and
upper mantle. Direct observations in these settings reveal that the spatial arrangement …
