Abstract
Detailed secular variation records of geomagnetic field direction during the Holocene, derived from archeomagnetic and sedimentary magnetic studies in Japan, can be used as a time scale for intervals of 102-103 years. Accumulated paleointensity data for the last 50kyr, from baked earth and volcanic rocks using the Thellier method, provide reliable age constraints for time intervals of 103-104 years. The geomagnetic excursions and short reversal events found in Japan, which mostly coincided with paleointensity minima at intervals of 104-105 years in the Pacific, are also useful for dating. Besides its chronological applications, magnetic analyses of sediments are useful in other areas of Quaternary studies.
