* = no solution possible with initial distribution (initial n in parentheses); results are reported for the dominant polarity. † = no solution possible. — = no lithologic unit. ISCI = in situ confidence index (see “Igneous petrology and volcanology” in the “Methods” chapter [Expedition 330 Scientists, 2012a]). NA = not applicable. The method of Arason and Levi (2010) was used to calculate inclination-only mean and associated statistics. α63 = circular standard deviation, α95 = 95% confidence angle.
