Geochemistry of lava, sediment, and ferromanganese oxides from petit-spot volcano and run products of hydrothermal experiment simulating petit-spot hydrothermal systems

This dataset consists of Table S1 to S6. Table S1 represents chemical composition of the fluid run products. Table S2 represents calculated potential metabolic energy in the mixture of seawater and fluid run product of hydrothermal experiment. Table S3 represents chemical composition of lava, sediment, and ferromanganese oxides from a petit-spot volcano. Table S4 represents Nd-Sr-Pb isotope ratios in sediment and ferromanganese oxides. Table S5 represents calculated chemical flux from global petit-spot hydrothermal systems. Table S6 represents chemical composition of fluids for metabolic energy calculation.
