| 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. PR95/22 is moderately consolidated, pinkish massive tuff. It was collected from a jointed unit several meters thick, about 8 m below the base of the basaltic sill. The unit sampled grades upward to a siliceous, possibly opaline zone. |
