We present a new empirical equation for estimating sulfur content in silicate melts at anhydrite saturation based on available experimental results and an updated sulfide-liquid by adding relevant data that were not previously used excluding controversial data. The fits of our equations to the calibration are within 10 percent error. Only total pressure, temperature, melt composition, parameters often known or can be reasonably assumed natural magmatic systems, required utilization equations. useful petrologic modeling including hydrothermal ore deposits. Several example applications effect decompression komatiite high Mg basaltic magmas ratio minerals immiscible sulfide liquids during fractional crystallization these provided.
