GRD00W2T0: Nummulites and fragments of nummulites comprise 15 to 20% of the sample. Matrix is 25% quartz silt, 15 to 20% pelletoids of micrite, and the remainder is sparrite. The sparrite crystals seem to be set in a finer micro-sparrite, as if they are clasts, but this could be an illusion. Parallel orientation of nummulite fragments. Some echinoid clasts identified. (J. Gee)
