Extended Data Fig. 7: Stepwise AF-demagnetization diagrams and vector end-point diagrams.

Data is provided for five representative subsamples (denoted specimens) from the Calio excavation site and the road section further east. The analysed specimens were taken from palaeomagnetic block samples Sp1, Sp2, Sp6, Sp7 and Sp9. The first sample number indicates the block sample number, whereas the second number refers to subsamples obtained from the block samples (e.g., Specimen 6-1 is the first subsample obtained from palaeomagnetic block sample Sp6). Open circles on the orthogonal projection indicate the vertical component of magnetization and the solid circles the horizontal component. Open circles on the equal area projection diagram indicate an upper hemisphere magnetic direction. Solid circles indicate a lower hemisphere magnetic direction.
