Figure F8. Photograph of interval 187-1156A-2R-2W, 58-65 cm, showing crosscutting relations between first- and second-generation micritic calcite with respect to the alteration halo in the lower basalt clast (see "Unit 1" in "Igneous Petrology"). Note the relatively fresh angular basalt clasts surrounded by second-generation micritic calcite, as well as the light colored, bleached-white palagonite surrounded by fresh glass. P = rounded yellowish orange palagonite clasts. The triangular vug is filled with third-generation sparry calcite.
