| 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. PR95/24 is dark gray, coarse-grained and massive melted and recrystallized vitrophyric pumice fall sampled at the contact with basalt. The bed sampled is about 20-30 cm thick, coarse-grained, contains silicified nodules of pumice fragments, and is poorly foliated parallel to the strike of the bed. |
