The effect of hydrothermal alteration on the seismic structure of the upper oceanic crust: Evidence from Holes 504B and 1256D

Geochemistry, Geophysics, Geosystems, 2011
It has long been argued but never demonstrated that alteration “fronts” should be recognizable features of the seismic structure of the oceanic crust. The abrupt transition from crust affected by low‐temperature hydrous alteration to crust affected by ...

Episodic Seafloor Hydrothermal Alteration as a Source of Stable Remagnetizations in Archean Volcanic Rocks

Geochemistry, Geophysics, Geosystems
Interpreting the paleomagnetic records of altered rocks, especially those from Earth's earliest history, is complicated by metamorphic overprints and recrystallization of ferromagnetic minerals.
