| Comment | Samples PR95/18-23 were collected below a 46 m thick basaltic sill sampled as PR95/29, about 0.6 km north-northwest from the locations of PR95/1-17. PR95/20 is hard, pinkish moderately welded massive tuff, with silicified clasts and abundant vitrophyre or obsidian clasts, welded pumice, and elongated vesicles. It was collected about 3 m below the base of the basaltic sill, where the rock is jointed and joint planes are coated with secondary minerals, including calcite and silica. |
