Figure F9. Close-up photograph of Unit 7, which consists of light gray to white, bleached, aphyric volcanic rock with preserved elongate vesicles. The core sample is pervasively bleached with a zoned alteration pattern toward a darker gray, less strongly bleached kernel (interval 193-1188A-9R-1, 16-29 cm).
