| Comment | Samples PR95/1-16 were collected along a line across a basaltic dike to determine alteration assemblages of tuffs intruded by basaltic dikes and sills at Paiute Ridge. PR95/9 is hard, recrystallized, crystal-rich dark to pinkish brown massive ash flow tuff with welded matrix glass from the same unit as described for PR95/1, 2.4 m NW from a 9.4 m wide basaltic dike sampled as PR95/16. The unit is jointed here. |
