Abstract
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.
