| Comment | Samples PR95/24-28 were collected from an 8.7 m thick basaltic dike trending N40W and along a 0.7 m thick pumice fall trending N55E. PR95/28 is medium brown, partially weathered fine-grained basalt with abundant tiny amygdules, possibly silica. Sampled about 45 cm from PR95/24. The dike is platy, jointed parallel to its strike, and the central part is eroded, the contacts with tuff forming walls. |
