Notes: Dec = declination,
Inc = inclination NRM = natural remanent magnetization, MDF = median destructive
field,
= magnetic susceptibility, Q-ratio = Koenigsberger ratio. A present-day field of
30 A/m was used for Q-ratio calculations. The basalt pieces are grouped into
paleomagnetic units as described in the text. This table is also available in ASCII
format.
