Abstract

The bulk mineralogical compositions of sediment samples from Sites U1325–U1329, northern Cascadia margin, were determined by X-ray diffraction analyses. The results document a highly variable mineralogy dominated by detrital components, mainly quartz, feldspar, mica, and clay minerals. Carbonate minerals are present only in minor amounts (<5 wt%). The long-term variations in the relative abundance of each mineral correspond to the particular lithostratigraphic units.
