V. Mejia et al., PALEOMAGNETIC FIELD INTENSITY RECORDED IN SUBMARINE BASALTIC GLASS FROM THE EAST PACIFIC RISE, THE LAST 69 KA, Geophysical research letters, 23(5), 1996, pp. 475-478
Paleointensity determinations were obtained from basaltic glass recove
red from the northern East Pacific Rise using the Thelliers' (1959) me
thod as applied by Pick and Tauxe The samples are up to (a)69 Ka old b
ased on their ridge axis and U-series disequilibria results show a gen
eral increase in paleointensity of the field from 69 Ka to the present
with values ranging from 50% higher than the present field to as low
as 26% The average dipole moment is 8.32 x 10(22) Am-2 which is simila
r to the present moment. The results are in general agreement absolute
and relative paleointensity records.
