Figure F3. A. 87Sr/86Sr in Hole U1380C carbonates (triangles) compared with ratios in pore fluids reported by Ross et al. (2015) (blue circles = Hole U1378B, green circles = Hole U1380C). B–D. Elemental composition of Hole U1380C carbonate samples (triangles) from soft leaching procedure compared with published pore water composition of fluids from Hole U1378B (blue circles) and Holes U1380A and U1380C (green circles) (Harris et al., 2013c; Torres et al., 2014). E–F. Downcore profiles of δ13C and δ18O in Hole U1380C carbonates (triangles) and corresponding pore water isotopic data for DIC and water for Holes U1378B (blue circles) and U1380C (green circles). Open triangles represent samples with heavier carbon isotopic values relative to the other carbonates (344-U1380C-41R-1, 50–52 cm; 42R-1, 30–31 cm; and 52R-2, 67–68 cm).
