Directions of the low-T and high-T components an the difference of the declination of ODP Site 124-770B (Table 1)

Experiments with thermal demagnetization of the samples from Site 770 of Ocean Drilling Leg 124 indicate that the samples have two magnetic components. An assumption that the low-temperature component, which is removed between 100°C and 200°C, is the secondary magnetization acquired in Brunhes normal chron, gives a core orientation. The oriented high-temperature component directions were tightly clustered around a pair of antipodal directions. The change of declination of the high-temperature component shows that the Celebes Sea was rotated counterclockwise about 60° during Eocene and Oligocene time.
