Sample ID	PR95/8
Rock name	TUFF
Rock type	VOLCANIC
Composition	FELSIC
Material	IGNEOUS
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. PR95/8 is fairly vesiculated light pinkish gray ash flow tuff with perlitic pumice from the same unit as described for PR95/1, 2.8 m NW from a 9.4 m wide basaltic dike sampled as PR95/16. The unit is jointed and forms a resistant ledge here, and is substantially harder than samples at locations PR95/1-7.
