Fig. 2.

(A) Orthographic projection diagrams showing AF and thermal demagnetization of three representative samples KH02-B, KH25-J, and conglomerate clast KH12–C23. Data are presented in geographic coordinates; closed symbols represent north–south–east–west projections, and open symbols represent up–down–east–west projections. Interpretations are shown with colored arrows: each arrow reflects a direction vector corresponding to components inferred from PCA. LCT = low-coercivity/low-temperature overprint, HT1 = high-temperature magnetite, HT2 = high-temperature hematite. (B) Stereographic equal-area projections showing HT1 directions for each sample (gray circles) and their site-means (red squares) with associated 95% confidence angles (black ellipses). Data are presented in geographic coordinates (Left) and after tilt correction (Right). Upward directions are denoted with open symbols, and downward directions are denoted with filled symbols.
