| 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. PR95/5 is ash flow tuff from the same unit as described for PR95/1, 12.0 m NW from a 9.4 m wide basaltic dike sampled as PR95/16. No physical changes were noted for this sample although it is closer to the intruding dike compared to samples PR95/1-4. |
