Summary:Boron isotope and concentration data are presented for hydrothermal fluids from different tectonic settings that reflect derivation of B from marine evaporites (Red Sea brines), non- marine evaporites (Salton Sea), clastic sediments (Escanaba Trough and Guaymas basin), back-arc basalts (Mariana Trough) and MORB (21 degrees N, MAR). Boron isotope systematics of these fluids are used to constrain the 11B-values of tourmalines found in ancient massive sulphide deposits and tourmalines that formed under conditions analogous to those of modern hydrothermal systems. The data also provide insights into the physical conditions required for the formation of tourmaline in certain geological environments. [Author's abstract] [P.Br.]
