We thank Levresse et al. (2017) for their comments on our work and for giving us the opportunity to clarify several points made in our article, “Basinal brines at the origin of the Imiter Ag-Hg deposit (Anti-Atlas, Morocco): Evidence from LA-ICP-MS data on fluid inclusions, halogen signatures, and stable isotopes (H, C, O).” The Imiter deposit has been studied for a long time, and the present discussion shows that controversywill continue, at least until indisputable direct dating of ore deposition is achieved.The main issues developed by Levresse et al. (2017) concern the validity of mineral and fluid succession, the significance of ages, the metallogenic models, the multistage feature of the ore formation, the nature of fluids, and their ability to transport Ag. These points are successively expanded in thefollowing paragraphs with the help of some diagrams.
