Figure 2-9. Unit C: X-ray radiographs of selected cores from lithologic unit C in MP288c1. Each picture is a reproduction of the X-ray radiograph negative. Light tones represent areas or features that are dense to the penetration of X-rays. The major clinoform set represented by unit C is sand-rich throughout. Massive and parallel-horizontal bedding is most common and represented by all the radiographs of this figure. Shell content increases stratigraphically upward, and oriented shell fabrics are observed near the top of the unit (radiographs a and b). Transported organic particles are missing as discrete layers in unit C. Note the numerous shell fragments scattered throughout each core sample. All cores are 7.6 cm in diameter.
