Figure F47. Physical property details from selected sections of Hole U1346A. A. Bulk GRA density through a sequence of sediments and basalts. Dark red triangles = discrete MAD measurements. B. Correlation of magnetic susceptibility and natural gamma ray (NGR) total counts per second from the Natural Gamma Ray Logger. C. Correlation of decreasing magnetic susceptibility at the change from gray to brown alteration (see "Alteration and metamorphic petrology"). Note the lack of change in bulk density through changing alteration styles. Light red circles = GRA density, dark red triangles = discrete measurements. D. Variation in magnetic susceptibility through a continuous section of core, perhaps related to changing mineralogical characteristics.
