Dear Colleagues, Please find attached information about a short course at GSA “Geochemical Modeling for Critical Minerals Resourcing and Processing”, to be led by Dr. Peng Lu (Saudi Aramco). The course is free of charge and provides an excellent introduction for students to the concepts of critical minerals and to how fundamental geochemical and mineralogical sciences connect with societal needs through geochemical modeling.
