Thin Sections:

GRD00T5T0: Slide 1: High porosity. Pelletal material in sparry matrix. The sparite becomes very coarse-grained and free of pellets when filling vugs. (C. Eichler)

GRD00T5T1: Slide 2: High porosity. Pelletal material in sparry matrix. Wormy texture in portions of the slide where calcite grew over curved surfaces and around pre-existing calcite crystals. No sparite filling the vugs, like Slide 1. (C. Eichler)
