Figure F31. Digital photograph of the >63-the P/E boundary, Section 199-1220B-20X-2. The following major grains are observed at each depth interval: Planktonic foraminifers (intervals 199-1220B-20X-2; 13-20, 28-35, 35-43, and 42-50 cm; 198.90-199.40 mbsf), pink brown grains and dolomite crystals (interval 199-1220B-20X-2; 50-57 cm; 199.40-199.47 mbsf), black grains and sediment lumps (interval 199-1220B-20X-2; 57-64.5 cm; 199.47-199.55 mbsf), large pinkish grains with many dolomite crystals (interval 199-1220B-20X-2; 65-72 cm; 199.55-199.62 mbsf), small pink brown grains with rare planktonic foraminifers and dolomite grains (interval 199-1220B-20X-2; 74-78 cm; 199.64-199.68 mbsf), and dolomite grains and rare benthic foraminifers (interval 199-1220B-20X-2; 77.5-85 and 85-95 cm; 199.68-199.85 mbsf).
