Description:
During Leg 125, scientists drilled three holes (782A, 784A, and 786A) in the Izu-Bonin forearc near 31° N that had sufficient recovery to obtain paleoinclination data. 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.
