Figure F34. Amount of alteration (vol%) vs. depth in Hole 735B (see the "Core Descriptions" contents list). The percentages were estimated by visual observation of the core, and metamorphic units are defined in the visual core descriptions. A. Rock alteration percent. The thick gray line is a running average (window: 10 samples). B. Percent of plagioclase alteration. Note that background hydrothermal and dynamically recrystallized plagioclase are not distinguished in hand specimens of deformed gabbros (e.g., 880-1070 mbsf). C. Percent of olivine alteration. D. Percent of clinopyroxene alteration. Note that orthopyroxene is not distinguished from clinopyroxene.
