Figure F30. Downhole plots of inclination, Holes U1377A and U1377B. A. Core recovery and observed stratigraphy (see Fig. F8 for explanation of patterns and abbreviations). B. All downhole inclination data measured at 2 cm intervals on archive-half cores: red = principal component analysis (PCA) directions with misfits ≤ 2.42 (Hole U1377A) and ≤ 1.89 (Hole U1377B), pink = PCA directions with misfits > 2.42 (Hole U1377A) and > 1.89 (Hole U1377B). C. Average inclination for each lithologic unit (see “Igneous petrology and volcanology”), calculated using inclination-only statistics (Arason and Levi, 2010). D. Average inclination for each core piece longer than 9 cm, calculated using Fisher statistics. E. Average inclination for each lithologic unit, calculated using average piece directions displayed in D and inclination-only statistics. F. Characteristic remanent magnetization inclinations from discrete samples (from alternating-field [AF] or thermal demagnetization) with maximum angular deviation ≤ 5°. Shading scheme for C–F represents the ISCI for identifying distinct lava flow units, where the darkest shade of blue is the most confident and green is not applicable (NA; i.e., deposits cannot have retained their orientation since cooling).
