| Description: | Pale buff, or cream-coloured, compact limestone with semicrystalline lustre. Composed of a matrix of clear calcite, of 0.05 - 0.3 mm grain, containing ooliths and numerous fairly well sorted calcareous pebbles, comprising subrounded fragments and knobby spheroids from 0.3 - 1.5 mm in size, perhaps of algal origin, subangular to rounded pieces of very fine-grained limestone containing ooliths and crinoid fragments but sometimes uniformly structureless, and rare crinoid ossicles. The rock is traversed by many thin calcite-filled cracks which show tensional rupture without lateral displacements. A few quartz grains are present in the matrix and in the semi-opaque limestone. Limestone, fine-grained, oolitic, pseudo-oolitic. SL0154. Britrocks S34656. Magnification x40. Light XPL. |
