Figure F3. Lithologic summary showing core recovery, lithologic unit, graphic lithology, calcareous intervals, diatom mats, and beds tentatively interpreted as turbidites in the four holes drilled at Site 1091. Calcareous intervals, diatom mats, and turbidites are only schematically represented (their true thicknesses are smaller than shown), with true thicknesses and locations in each core accurately represented in the Site 1091 core correlation diagram (Fig. F6, p. 25). Numbers above turbidite beds correspond to designations in the core correlation diagram (Fig. F6). T.D. = total depth. (Continued on next page.)
