Fig. 2 in A serpulid-Anodontia-dominated methane-seep deposit from the upper Miocene of northern Italy

Fig. 2. Petrographic character of the late Miocene Ca' Fornace seep deposit, Italy, illustrated by scanned thin sections (A, B) and thin section micrographs (C–F). A. Cavity in micrite (m), lined with banded and botryoidal cement (bbc), and filled with fecal pellets (fp) in the upper part and micrite in the lower part. B. Serpulid tubes cemented by micrite. C. Close-up of section in A, showing banded botryoidal cement (bbc), micrite (m), fecal pellets (fp), and clumps of pyrite (p). D. Close-up of section in B, showing details of the serpulid tubes. E. Sponge fabric (sf) around bivalve shell. F. Close-up of sponge fabric, also showing scattered pyrite framboids (p).
