Abstract

Carbonate content and mineralogical composition of sediment samples from Integrated Ocean Drilling Program Sites U1325–U1329 in the northern Cascadia margin were determined. The results document their low carbonate content (average ≈ 2–3 wt%), with decreasing values with distance to the shoreline. Carbonate content and carbonate mineralogy (calcite, dolomite, aragonite, siderite, and rhodochrosite) of 85 authigenic carbonate samples were also determined.
