Question

This property is progressively reduced in experiments whose results are displayed on vector component plots named for J. D. A. Zijderveld (“ZAY-der-felt”). The high strength of one form of this phenomenon is indicated by Koenigsberger ratios above one. Whether this property’s namesake “fabric” appears linear or planar is used to classify grains as MD (-5[1])or SD. Materials with one form of this property obey the laws of “reciprocity,” “independence,” and “additivity” according to the Thellier (“tell-YAY”) laws. Rocks with this property (15[1])are used to identify APWP tracks, which have led to the discovery of events like the (*) Brunhes–Matuyama (“broon ma-tsu-ya-ma”) event. (10[3])Layers of chert (10[1])alternate with layers of a mineral with this property (10[1]-5[1])in banded iron formations. (10[2])The Vine–Matthews–Morley (10[1])hypothesis predicted the presence of symmetrical “stripes” of rock with this property near (10[1])mid-ocean (10[1])ridges due to seafloor spreading. For 10 points, give this property that lends its name to the iron ore with chemical formula Fe3O4 (10[1])■END■ (10[1])
