Figure F12. Images of pyrite in silty and sandy lithologies in plane-polarized light. A. Heavily pyritized silt with pyrite as disseminated framboids (Sample 338-C0022B-7H-2, 89 cm). B. Pyrite as grain coatings and minute (near clay size) framboids (Sample 338-C0022B-20X-1, 48 cm). C. Pyrite framboids localized along a possible burrow structure (Sample 338-C0022B-38X-1, 18 cm).
