GRD01NWT0: Slide shows three different limestones. One half of the slide is a fine-grained crystalline carbonate. The fine-grained carbonate is in contact with a bedded, pelletal limestone. The pelletal limestone is separated from a shelly, pelletal micrite by a styolite. The micrite contains radiolarians. (C. Eichler)
