abstract

  • Magnetic properties (natural remanent magnetization (NRM), susceptibility (χ), Curie point temperature (Tc), saturation isothermal remanent magnetization (IRMs), and Koenigsberger ratio (Q)) and opaque mineralogy were determined for basalts, diabases, gabbros, peridotites, and serpentinites collected by dredging and submersible from the rift valley at five hydrothermal sites (15°N, 17°N, 23°N (the Snake Pit hydrothermal field), 26°N (the TAG hydrothermal field) on the Mid-Atlantic Ridge, and 42°N (the Sea Cliff hydrothermal field) on the northern Gorda Ridge). The magnetomineralogy is interpreted in terms of deuteric, hydrothermal, metasomatic, and ambient seawater alteration. -from Authors
