| Description: | Compact, grey limestone composed of finely granular calcite, 0.01 - 0.1 mm grain-size, enclosing debris of small shells, foraminifera, vermiform algae encrusting crinoid and shell fragments, small bodies giving horned hemispherical sections, occasional larger fragments of crinoid and shell and thin-walled bodies, apparently ostracods. Limestone, micrograined, microfossiliferous, clastizoic. S 34530. Compact, darker grey limestone containing larger and less recrystallized organic remains than S 34529.
