Figure F4.
Summary figure for Site 1200 including lithology, color reflectance, and
calcareous intervals. Yellow intervals in the "Unit" column indicate
intervals of Facies I. Light blue intervals in the same column indicate
intervals of Facies II. Color reflectance parameter b* measures the amount of
reflectance in the blue vs. yellow spectra. Carbonate intervals were identified
using 10% HCl acid tests at regularly spaced intervals. Color reflectance values
correlate well with carbonate intervals; however, the overall heterogeneity of
the material produces spectral peaks in noncalcareous intervals. TD = total
depth. See Figure F4
in the "Explanatory Notes" chapter for a key to the lithology symbols.
