Figure 3. Mineral and opal data for the upper 400 m of Hole 1082A. A. Opal XRD counts (dashed line) compared with diatom abundance (solid line; see "Biostratigraphy and Sedimentation Rates" section, this chapter). B. Ratios of albite (solid line with filled circles), microcline (solid line), and muscovite to quartz (mineral/[mineral+quartz]; dashed line). C. Opal (dashed line) and quartz (XRD counts; solid line).
