Figure 2. Lithostratigraphy and stratigraphic position of ash-bearing sediments of the lower Pliocene-Oligocene sedimentary sequence recovered at Sites 982 and 985 (Shipboard Scientific Party, 1996a, 1996b; stratigraphic boundaries with minor revisions after Spiegler, Chap. 3, this volume). Dashed lines indicate highly altered ash. For hole-to-hole correlation, see Table 3.
