| 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. PR95/6 is ash flow tuff from the same unit as described for PR95/1, 7.8 m NW from a 9.4 m wide basaltic dike sampled as PR95/16. No changes in hardness or color were noted for this sample although it is closer to the intruding dike compared to samples PR95/1-5. Jointing is apparent at the sample site. |
