Project Details
Description
The high-temperature geochemical properties of chalcophile ( sulfur-loving ) elements including Pb and the noble metals will be investigated experimentally in magmatic sulfide systems, as a function of temperature, pressure, composition and sulfur and oxygen fugacities, using new techniques to solve the experimental problems that have plagued earlier measurements. An experimental innovation to handle volatile elements will allow for the first time the determination of the partitioning of Pb and other volatile and chalcophile elements between sulfide and silicate melt, to test the recent hypothesis that retention of Pb in sulfides may resolve the Earth s Pb paradoxes , long-standing enigma in chemical geodynamics.
