D-Compress computes the gas and melt volatile composition of five element sets in magmatic systems (O–H, S–O–H, C–S–O–H, C–S–O–H–Fe, and C–O–H). It has been calibrated so as to simulate the volatiles coexisting with three common types of silicate melts (basalt, phonolite, and rhyolite). Operational temperatures depend on melt composition and range from 790 to 1400 °C. A specificity of D-Compress is the calculation of volatile composition as pressure varies along a (de)compression path between atmospheric and 3000 bars. Theory, use, and limitations of D-Compress are described in Burgisser, A., Alletti, M., Scaillet, B. (2015) Simulating the behavior of volatiles belonging to the C-O-H-S system in silicate melts under magmatic conditions with the software D-Compress, Computers & Geosciences:79,1-14.
