Summary figure for Site 1201 including lithology, units and facies, color
reflectance, natural gamma count, and mineral composition. The color reflectance
parameter a* measures the amount of reflectance in the green vs. red spectra.
Natural gamma counts were obtained from physical properties measurements
performed on the MST. Mineral composition is derived from a compilation of
results from smear slide, thin section, and XRD analyses. All parameters
coincide well with the lithostratigraphic boundary between Units I and II. Color
reflectance data is consistent with facies changes that are associated with a
change of color, whereas the natural gamma counts reflect both the large-scale
and the tightly packed multiple fining-upward sequences found throughout the
succession. In the graphic lithology log, c = clay, s = silt, s = sand, g =
gravel.
