Five different samples: four are uncut in a plastic bag. One sample is cream-colored and vuggy with calcite filling-in the vugs. Another sample is a very fine-grained blue-green mudstone. Another is pink veins cross-cutting fine-grained white mudstone. The last sample is pink with light pink and brown clasts (volcaniclastic?) - similar to cut piece. The cut sample is not in the bag. It is cut into three pieces, one of which is a billet. White cross-cutting veins and brown clasts in fine-grained pink matrix. |
