Chlorine, Fluorine, and Bromine fluid/melt partitioning data in basaltic andesite and dacite rock experiments
The data report new F, Cl, and Br fluid/melt partition coefficients for intermediate to silicic melts, for which F and Br data are particularly lacking; and for varying CO2-H2O contents. The data was collected from basaltic andesite and dacite rock experiments from the Kelud volcano in Indonesia and Quizapu volcano in Chile Over the period of two years, 2020 – 2022. The experiments were conducted at pressures 50–120 MPa, temperatures 800–1100 °C, and volatile compositions [molar XH2O = H2O/(H2O +CO2)] of 0.55 to 1, with redox conditions around the Nickel-Nickel Oxygen buffer (ƒO2 ≈ NNO). Experiments were not doped with Cl, Br, or F and were conducted on natural crystal-bearing volcanic products at conditions close to their respective pre-eruptive state. The data was collected to assess the effects of changing fluid composition (XH2O) on Br fluid/melt partitioning for the first time. Three tables of data are provided; Table 1.xlsx Table 1 Experimental conditions, which were conducted under NNO oxygen buffer.
