Figure 4. Area plots showing depth variations in detrital modes for turbidite sands from Sites 1023, 1024, and 1025 (Hydrothermal Transition Transect). Numbers refer to ages (in Ma) of nannofossil datums (from Su et al., Chap. 4, this volume). Q = total quartz; F = total feldspar; L = unstable lithic fragments; Qp = polycrystalline quartz; Lv = volcanic-rock fragments; and Lsm = sedimentary-rock and metasedimentary-rock fragments.
