| 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. PR95/13 is melted and recrystallized crystal-rich dark gray ash flow tuff from the same unit as described for PR95/1, 1.25 m SE from a 9.4 m wide basaltic dike sampled as PR95/16. The unit is broken into thin plates parallel to the strike of the dike here. |
