Figure 16. Summary of lithostratigraphic units, alteration style, and distribution of alteration phases at Site 1188. Occurrences of relict igneous plagioclase are also represented (on the right side). Pyrite is present in all samples studied and is not represented on the figure. Clay phases are mentioned where detected by X-ray diffraction (XRD); no indication of their abundance relative to other phases is implied. EOH = end of hole.
