Abstract

Paleomagnetic data from three sedimentary sections at a locality in western California (U.S.A.) is reported. Natural rema- nent magnetization directions obtained from 61 oriented cores showed a magnetic component different from the present geomag- netic field. The characteristic remanent magnetizations (ChRM) show oblique normal, oblique reverse and reverse polarities during the Middle Holocene. The transitional VGP resembles those registered during Early and Middle Holocene in central Mexico and other areas of the Northern and Southern Hemispheres.
