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. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.762906"!
