Figure F35. Thin section photomicrographs of microfossils, Site U1374. A. Planktonic foraminifer Globotruncanita cf. conica (Sample 330-U1374A-2R-4, 27–32 cm; Thin Section 111). B. Geopetal structure in a foraminiferal bioclast limestone (Sample 330-U1374A-3R-1, 70–72 cm; Thin Section 113) (plane-polarized light). Mold of dissolved shell fragment can be seen, including (1) vadose silt and (2) dogtooth and granular cements. Dissolution of shells and vadose cements occurred probably after the lithification of the limestone. Arrow points toward top.
