A volcanic sequence almost 700 meters thick has been sampled in the Punaruu valley on the island of
Tahiti, southern central Pacific Ocean. Detailed paleomagnetic results have been obtained from 123 sites. Three
reversals are recorded in this sequence. Age determinations (K-Ar) indicate that the youngest reversal corresponds
to the...
We report paleointensity results of the Earth's
magnetic field from n Late Pleistocene lava flow
(Louchadiere, Central France), which recorded an intermediate
geomagnetic field direction (5 sites, mean declination=
114.1°, inclination=58.2°, k=130, α95=6.7°). New K-Ar
age determinations confirm that this flow is contemporaneous
with the Laschamp and Olby flows, and...
