GRD01PQS0 Sedimentary Dikes Decent-sized hand sample. Billet. Thre types of limestone: red, cream, and grey. Red is fine-grained and transitions to the cream limestone. Cream is micritic. Grey appears to be brecciated blocks. Calcite veins and a single vug on cut surface. Original label: Section across sill. B sits on top of A. C is separate and highest. Italy 1 Ritter 154, 22 K
GRD01PRS0 Cements Decent sized hand sample of cream and red limestone with calcite veins. Billets. Three thin sections from different parts of the sample. Original description: The breccia may be (?) related to breccias at bases and tops of other sills. Italy 3 Ritter 154, 23 K
