Table 4 Percentages of Zn (DZn) and Pb (DPb) dissolved in seawater relative to the initial sulfide sample

From: Onboard experiment investigating metal leaching of fresh hydrothermal sulfide cores into seawater

    DZn (%) DPb (%)    DZn (%) DPb (%)
CKL-1 Anoxic 5 °C 0.0036 0.0053 Oxic 5 °C 0.0015 0.0038
20 °C 0.0050 0.0077 20 °C 0.0035 0.0067
CKL-2 Anoxic 5 °C 0.12 0.026 Oxic 5 °C 0.047 0.015
20 °C 0.15 0.049 20 °C 0.018 0.021
CKL-3 Anoxic 5 °C 0.11 0.98 Oxic 5 °C 0.35 1.2
20 °C 0.19 2.3 20 °C 1.1 4.1
CKL-4 Anoxic 5 °C 0.11 0.063 Oxic 5 °C 0.25 0.079
20 °C 0.14 0.17 20 °C 0.42 0.28
  1. These values for all samples were calculated from the Zn and Pb concentrations in the seawater after reaction for 18 h because the pH of the CKL-4 solution decreased greatly to 4.5 under oxic conditions at 20 °C during 18–30 h and dissolution of Zn and Pb was greatly promoted under these conditions
