Figure F131. A. Close-up core photograph showing a small "breccia pipe" and sill/sediment contact in the lower sill complex (interval 210-1276A-97R-3, 138-150 cm). B. Thin section photomicrograph of the sill/sediment contact (plane-polarized light) (Sample 210-1276A-97R-3, 140.5 cm). C = contact, G = glassy matrix, S = sediment, V = vesicle.
