Session: Mineralogy of human-modified environments

Geologically unusual or novel minerals (and mineral assemblages) can be created through human alteration of terrestrial and aquatic environments, as a result of industrial processes such as mineral processing, desalination, manufacturing, and anthropogenic disturbance of natural systems and biogeochemical cycles (e.g. dewatering, land use change, dredge disposal, accelerated mineral carbonation). Managing the environmental impacts of human activities requires a detailed understanding of the composition, structure, reactivity and stability of these novel/unusual minerals and assemblages, and incorporation of this information in expanded mineralogical and geochemical databases and models to improve our predictive abilities. This session seeks contributions related to the characterisation (structure, thermodynamics, and dissolution/precipitation kinetics) of novel minerals or unusual mineral assemblages resulting from human modification of Earth surface environments or industrial processes. Studies involving structure solution and refinement, and investigations of thermodynamic and kinetic properties of minerals in anthropogenically influenced environments are welcomed.
