Fluid-mineral-microbe interfacial processes control all biogeochemical element cycles on Earth. Being able to follow dynamic (bio)mineral nucleation, growth or transformation reactions through high-resolution microscopic and spectroscopic methods helps us to improve our fundamental knowledge about what controls interactions during phase (trans)formation. Based on nanoscale observations on various Earth materials (incl. iron oxides, carbonates and sulphates) I will show how we validate and constrain reaction pathways most often inferred from empirical observations of natural geologic processes and how such nanoscale studies helps us model local to global scale element cycles.
