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 "Effects of substrate composition and subsurface fluid pathways on the geochemistry of seafloor hydrothermal deposits at the Lucky Strike Vent Field, Mid-Atlantic Ridge". 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.
