[SEM19-P02] Paleomagnetic study on the transitionally magnetized volcanic rocks from the Tahaa Island, French Polynesia
To further characterize the paleomagnetic behavior recorded in the lava sequence, a follow-up sampling was done in 2014. We collected ~50 new mini-core samples from the sequence, and in addition, 10 new mini-core samples were drilled from a single lava flow of a vicinity lava sequence, which corresponds to the site TA01 in the previous study (K-Ar age of 3.14 +/- 0.06 Ma; Uto et al., 2007). These mini-core samples were cut into specimens and they were subjected to paleomagnetic measurements including the Tsunakawa-Shaw absolute paleointensity experiments. We will report these results together with the previous results which are reanalyzed by a latest scheme.
