The Effects of Alteration on the Natural Remanent Magnetization of Three Ophiolite Complexes: Possilion years), Troodos Massif, Cyprus (~ middle Cretaceous), and Smartville complex, California (~Jurassic). The magnetic properties of the pillow basalts strongly depend on their degree of alteration. From the least altered, low-temperature- oxidized, upper pillow basalts of Macquarie Island and the

On the Origin of Stable Remanence in Pseudo-Single Domain Grains, alloys and yttrium iron garnet crystals. These studies support the basic contention that the role of surface anistropy is indeed the predominant one in explaining the high coercivity of PSD grains. These studies also provide useful experimental models for future research in this area in rock magnet

Reduction of Hematite to Magnetite under Natural and Laboratory Conditions,ay occur in air. Reduction produces undesirable effects during thermal demagnetization procedures and paleointensity determinations on samples containing hematite, but these effects can be eliminated or controlled if certain precautions are followed.

The Thermoremanence Hypothesis and the Origin of Magnetization in Iron Meteorites,table paleoremanence. 2) The NRM coercivity spectra, which are considerably harder than laboratory TRM’s in the finest structured groups, gradually soften as grain-size coarsens. 3) All magnetization directions (NRM, TRM, SM) in octahedrites appear to be preferentially associated with the octahedral

The Effects of Alteration on the Natural Remanent Magnetization of Three Ophiolite Complexes: Possilternating fields decreases. For the most altered pillow basalts of the Smartville complex the NRM is probably predominantly a VRM, acquired during the present polarity epoch. Thermomagnetic analyses for the least altered pillow basalts exhibit the characteristic behavior of low-temperature-oxidized

The Demagnetization Field of Multidomain Grains,h increase in remanence in multidomain grains. Although . can be approximated by a constant in the limit of small displacements of domain walls from their demagnetized sites, this constant critically depends on the domain geometry.
