| 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. PR95/14 is pinkish massive ash flow tuff with quartz, feldspar, and biotite, from the same unit as described for PR95/1, 2.85 m SE from a 9.4 m wide basaltic dike sampled as PR95/16. The matrix is supported by pumice and lithic fragments. The unit is cut by horizontal and vertical joints here. |
