Figure F74. Filtered whole-core magnetic susceptibility measurements. All measurements of pieces smaller than the sensing interval of the susceptibility loop, as well as all measurements within 5 cm of the end of a piece, have been removed. A simplified graphic lithology column, highlighting only those intervals where Fe-Ti oxide has been reported, is plotted to the left. Lithologic unit boundaries are also shown adjacent to the graphic lithology plot and embedded in the magnetic susceptibility plot. The dashed line represents a weighted moving average through the magnetic susceptibility data. Lithologic unit average magnetic susceptibilities are Unit I, 828 SI; Subunit IIA, 3406 SI; Subunit IIB, 3010 SI; Unit III, 780 SI; Unit IV, 3472 SI.
