Abstract

Sand samples collected from cores recovered at Sites C0004, C0006, C0007, and C0008, Integrated Ocean Drilling Program Expedition 316, are dominantly feldspathic litharenites containing between 18% and 40% detrital quartz within the total quartz, feldspar, lithic (QtFL) fraction. The lithic component includes a mix of volcanic, sedimentary, metamorphic, and plutonic fragments. The feldspar component is dominated by Ca-plagioclase. A grain-size control on modal composition is apparent, notably a greater concentration of feldspar grains in the finer samples. No significant stratigraphic or geographic trends in modal grain composition are observed within this sample set.
