Paleomagnetic Investigation of Leyte and Biliran Island, Central Philippines
Abstract
Six sample sites were chosen from over 20 sites located on Biliran and Leyte islands in the central Philippines to determine whether or not rotations associated with either a collision between the Palawan continental terrane and the Philippine Archepelago or fault movement along the Philippine Fault had occurred. Sample analysis using a normalized sample magnetization as a function of demagnetizing field strength graph and a Zijderfeld diagram indicated that the samples were demagnetizing properly. Older sites, JL-71 and JB-37 showed clockwise rotation associated with an island arc collision, while younger samples, JB-17, JB-3, and possibly JL-26 indicated counterclockwise rotation in agreement with fault-related rotations.
