Subject category Comment text
Deposit DARK GREY TO PINKISH-GREY STRINGERS OF PERLITIC GLASS OCCUR IN INCREASING ABUNDANCE UP-SECTION UNTIL THE PERLITE BECOMES A 100-200 FT THICK, CONTINUOUS LAYER. THIN SECTIONS OF THESE UNITS REVEAL A HYPOCRYSTALLINE TEXTURE WITH 60 TO 80 PERCENT GLASS. THE GLASS IN THE PERLITE IS FRESH EXCEPT FOR SLIGHT ALTERATION ALONG PERLITIC CRACKS AND CONTAINS ABUNDANT TRICHITES BUT NO TRACE OF SHARDS OR FLOW TEXTURE.
