Figure F12. Lithostratigraphic summary column for Site 1179. Core recovery is shown in left columns, with solid blocks indicating the amount of recovered core. Lithology and lithostratigraphic unit columns show generalized stratigraphy. Lightly shaded bands in Unit I lithology denote ash layers. Color reflectance, magnetic susceptibility, and natural gamma-ray columns show data measured on the archive multisensor track (color reflectance) and multisensor track (others). Curves in the far right column are from downhole logs. Magnetic polarity is shown by black (normal polarity) and white (reversed polarity) bands. Chron age designations are given next to the polarity column.
