Figure F8. Complex mineralized hardground in bioclastic packstone of Unit VI. Note the succession of two densely spaced firmground to hardground surfaces and the high content of large bioclasts, fossils, vugs, and burrows, notably in the upper part. The material infilling the shell to the upper left differs from the surrounding sediment, indicating an earlier fill period, reworking, and embedding during renewed sedimentation (interval 182-1132C-31R-CC, 0-15 cm).
