Figure F31. Example of remanent magnetization directions from AF demagnetization of archive half of Section 330-U1373A-7R-2. Directions were determined using principal component analysis (PCA). Dark blue = declinations for PCA directions with misfits below threshold of PCA fitting quality, light blue = declinations with misfits above threshold. Dark red = inclinations for PCA directions with misfits below threshold of PCA fitting quality, light red = inclinations with misfits above threshold. Open circles with error bars = piece-average directions, triangle = inclination from AF-demagnetized discrete sample, square = inclination from thermally demagnetized discrete sample. To avoid edge effects, data acquired within 4.5 cm of either piece end were filtered out.
