| 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. PR95/7 is massive ash flow tuff from the same unit as described for PR95/1, 4.4 m NW from a 9.4 m wide basaltic dike sampled as PR95/16. The sample is less weathered in cavernous fashion, slightly more pinkish in color, and substantially harder than samples PR95/1-6. |
