Figure F121. Magnetic susceptibility of Core 176-735B-161R. Locations of felsic veins numbers 246, 248, 249, 250, 251, and lithologic intervals 785 and 787 correlate directly with susceptibility peaks, Lithologic intervals 785 and 787 are 8- and 13-cm-thick oxide gabbros with 5 and 3 modal% opaques, respectively. Uncorrelated peaks likely correspond to oxide-rich intervals thinner than 5 cm, which were not logged.
