| Research Abstract |
We applied alternating field demagnetization and re-measurement to the samples from the Sue-type kiln which had been already measured and stored since 1960s. Paleointensity study using the kiln sample was also started Archeomagnetic data so far published were collected and assembled as a new database simultaneously. We compiled a new archeomagnetic database of Japan including well-dated and well-located data from 682 sites collected from old database and some excavation reports. Based on the new database, we constructed a new geomagnetic secular variation model of Japan during the past 2000 years.
