Bulk geochemistry and in situ sulfur isotopes of hydrothermal deposits from the Lucky Strike vent field, Mid-Atlantic Ridge

This is the dataset presented in the article <em>"Effects of substrate composition and subsurface fluid pathways on the geochemistry of seafloor hydrothermal deposits at the Lucky Strike Vent Field, Mid-Atlantic Ridge". </em>This includes Tables 1 and 2 found in the article as well as Tables S1 and S2 from the Supporting Information. Table 1 is the chemical composition of hydrothermal samples from the Lucky Strike vent field and Table S1 is an extended version of Table 1 that includes elements that were largely below the detection limit. Table 2 is the dataset for in situ sulfur isotope analyses of marcasite, pyrite, and chalcopyrite for samples from Lucky Strike. Table S2 is a compilation of modern seafloor hydrothermal sites that includes Lucky Strike, Menez Gwen, TAG, Snake Pit, Broken Spur, Rainbow, Logatchev, Beebe, Kairei, Yuhuang-1, and Daxi.
