IN order to investigate the effect of the deformation associated with mountain building upon the aniso-tropy of susceptibility and the natural remanent magnetization of rocks, approximately a hundred ...

A crater may disappear long after a meteorite impact, but a new method of finding impact sites despite this has been uncovered. Gunther Kletetschka of the University of Alaska Fairbanks Geophysical ...

If you could pick up a rock from the surface of Mars, then the chances are it would be magnetic. And yet, Mars doesn't have a magnetic field coming from its core. These rocks are clinging to the ...

THE intensity of isothermal remanent magnetization of a ferromagnetic body usually increases with its cooling in non-magnetic space, owing to increase in spontaneous magnetization. We have found, ...

Many of these rocks showed signs of strong natural remanent magnetization, or NRM. Additional spacecraft data confirmed widespread crustal anomalies—especially on the moon’s far side—that point to the ...

An asteroid that has been wandering through space for billions of years is going to have been bombarded by everything from rocks to radiation. Billions of years of traveling through interplanetary ...

The characteristics of the remanent magnetization of chondrite, achondrite and shergottite, nakhlite and chassignite (SNC) meteorites are described, and interpretation in terms of magnetizing fields ...

An electromagnet can be used to attempt to magnetize a few different cores, including a steel core, a soft iron one, and an aluminum one. Different objects can be picked up by the magnetizable cores, ...
