Notes: Because of the presence of maghemite, alternating-field demagnetization may be insufficient to clearly separate multiple directional components that could compose the natural remanent magnetization of basement Units 1 and 3 (see "Discussion" in "Paleomagnetism and Rock Magnetism"). Estimate of dispersion (S), based on the transformation of Cox (1970) = 17.3°. N = number of determinations within each unit. Point inc = estimation of the inclination mean based on the averaging method of McFadden and Reid (1982). Inc₉₅ = estimation of 95% confidence interval of inclination. k = estimate of precision parameter. N for "Average" values is the estimated number of independent time units (see text).
