Figure 9. Ternary diagrams showing a comparison among mean detrital modes for sand deposits from the Leg 168 study area (from Saettler, 1998), Site 174 of the DSDP (from Marsaglia and Ingersoll, 1992), and Site 177 of the DSDP (from Gergen and Ingersoll, 1986). Q = total quartz; F = total feldspar; L = unstable lithic fragments; Qm = monocrystalline quartz; P = plagioclase; K = potassium feldspar; Qp = polycrystalline quartz; Lv = volcanic-rock fragments; Lsm = sedimentary-rock and metasedimentary-rock fragments; L m = metamorphic-rock fragments. Boundaries for tectonic provenance fields are from Dickinson and Suczek (1979), Dickinson et al. (1983), and Ingersoll and Suczek (1979).
