Figure F20. Calcium carbonate rates and carbonate and terrigenous mass accumulation rates (MAR) for Sites 1123 (water depth = 3290 m; North Chatham Drift) and 1124 (water depth = 3967 m; Rekohu Drift), based upon downhole log profiles (after Handwerger and Jarrard, in press). PCA = principal component analysis. Position of paraconformities is indicated by vertical arrows and accompanying italic text (upper two diagrams). See caption to Figure F6 for key to New Zealand biostratigraphic stage abbreviations. See text for detailed comments.
