| Description: | A black, compact, fine-grained limestone showing conchoidal fracture; specks of pyrite and crinoid columnals are sparsely distributed. Composed of a turbid, very fine-grained matrix of calcareous fossil debris, calcite granules, 0.005 mm, and probably some clay, in which are numerous fragmentary large and small shells, crinoid columnals, foraminifera, spines and polyzoa. Small opaque granules and wisps, fairly abundantly distributed, are largely carbonaceous, but some are of pyrite. Shreds of bleached mica are present. Limestone, argillaceous, pelitomorphic, fossiliferous, clastizoic. SL0159. Britrocks S34859. Magnification x40. Light PPL. |
