• Self‐reversal of magnetization in oceanic submarine

  1. Introduction 2 Titanomagnetite Fe 3−x Ti x O 4 (0 < x < 1) with x = 0.6 is the most abundant primary magnetic mineral in submarine basalts. The thermoremanent magnetization (TRM) acquired by titanomagnetites at mid‐ocean ridges leads to the oceanic magnetic stripes that provided major evidence for plate tectonics in the early 60 s.

  Introduction. The abundance and distribution of H 2 O within the terrestrial planets as well as its timing of delivery is a topic of vital importance for understanding the chemical and physical evolution of planets and their potential for hosting habitable environments. Over the last decade the prospects for H 2 O in our inner solar system have increased with the discovery of H 2 O on the

• Paleomagnetic evidence for modern-like plate motion

  The mode and rates of tectonic processes and lithospheric growth during the Archean 4.0 to 2.5 billion years (Ga) ago are subjects of considerable debate. Paleomagnetism may contribute to the discussion by quantifying past plate velocities.

• On the intensity and stability of the natural remanent

  The primary magnetic mineral in the newly constructed crust at the mid-ocean spreading centres is titanomagnetite. This becomes progressively maghemitized under the physical and chemical conditions which prevail in the submarine crust and it is believed that it is this process which is largely responsible for the striking fall in intensity of the remanent magnetization of sea-floor basalts
