Plate P1. A. Foraminifers in dolomicritic groundmass. Foraminifer chambers are partially filled with calcite or dolomite cement (Sample 201-1227A-8H-CC, 30–36 cm; 62.9 mbsf). B. Groundmass consisting of euhedral decimicron-size dolomite rhombs (Sample 201-1227A-12H-1, 85–88 cm; 101.4 mbsf). C. Curve-shaped crystal surfaces in coarse-grained dolomite (Sample 201-1227A-13H-1, 28–30 cm; 110.4 mbsf) are probably the result of cemented skeletal fragments. D. Foraminiferal test in a microsparitic dolomite groundmass. The perforate structure of the foraminiferal test is well preserved and probably still consists of biogenic calcite, whereas chambers show coarse fringes of isopacheous, blocky (probably dolomitic) cement on the inside (Sample 201-1227A-13H-1, 28
