The intrinsic properties of the elements and their resulting behavior in natural systems represent the underpinnings of geochemistry as a scientific discipline (Goldschmidt 1937). One of the most valuable intrinsic properties of an element is its volatility. The volatility of an element is most commonly expressed as a 50% condensation temperature, which corresponds to the temperature at which 50% of an element would have condensed from a gas of solar composition at nebular total pressure of 10–4 bars (e.g., Lodders 2003). Refractory elements are characterized by high condensation temperatures with the inverse being true for more...
