Ys. Kok et L. Tauxe, SAW-TOOTHED PATTERN OF SEDIMENTARY PALEOINTENSITY RECORDS EXPLAINED BY CUMULATIVE VISCOUS REMANENCE, Earth and planetary science letters, 144(3-4), 1996, pp. 9-14
The relative paleointensity of the earth's magnetic field from ODP Sit
e 851 has been characterized by progressive decay towards polarity rev
ersals, followed by sharp recovery of pre-reversal values [1]. We resa
mpled the Gilbert-Gaup reversal boundary of this deep-sea core, and sh
ow that during demagnetization this 'saw-toothed' pattern disappears.
Further, the recently published Cumulative Viscous Remanence model [2]
using the herewith obtained paleointensity record and constraints fro
m thermal treatment replicates the saw-tooth of [1], implying that it
is of non-geomagnetic origin.
