Figure F37. (A) Core recovery and stratigraphy of Hole U1376A, with (B, C) representative close-up core photographs of geopetal structures. (B) Numerous horizontal geopetal structures within limestone of Subunit IIA (interval 330-U1376A-4R-3A, 3–8 cm [wet]). These geopetals have a pink micrite lower layer, with the remainder subsequently completely or partially filled by calcite. (C) Geopetals within this large clast have dips of up to 8° on either side of horizontal, resulting in an overall average of ~0° (interval 5R-1A, 78.8–84.5 cm [dry]). For explanation of lithology symbols, see Figure F10.
