Paleomagnetic of ODP Leg 125 holes

A total of 169 paleomagnetic samples were analyzed using either alternating field or continuous thermal demagnetization. Unfortunately, poor recovery, complex magnetization in the older sediments, and dipping beds prevented us from obtaining results that were older than middle Miocene.

However, six reliable data points (one Pleistocene, three Pliocene, and two Miocene) were obtained. These data agree with past work from around the Philippine Sea plate, which suggest about 20° of northward translation since the Eocene. This paleomagnetic data set can be used to help constrain models for the origin and history of the Philippine Sea plate.
