After more than 100 years of intense prospecting, ore deposits with a surface expression or a characteristic geophysical signature have been discovered. As a result, the industry needs innovative and quantitative exploration techniques. Geochemical exploration suffers from a growing gap between ever more powerful geochemical analytical capabilities and the poor understanding of fundamental processes in hydrothermal systems. By combining new experiments on important geochemical systems (association between the trace elements Te and As with Au) with advances in numerical modelling of H2O-CO2-NaCl fluids, the project aims to bring geochemical exploration in line with geophysical exploration.

经过100多年的紧张勘探，已发现具有地表表现或特征地球物理标志的矿床。因此，该行业需要创新的定量勘探技术。地球化学勘探因日益强大的地球化学分析能力与对热液系统基本过程的认识不足之间的差距越来越大而受到影响。该项目将重要地球化学系统（微量元素Te和As与Au之间的关系）的新实验与H2O-CO2-NaCl流体数值模拟的进展相结合，旨在使地球化学勘探与地球物理勘探相一致。
