Mechanisms of Mineral Replacement Reactions (DELTA-MIN)

Basic data for this project

Description

The research themes of Delta-MIN relate to the mechanisms of mineral reequilibration (phase transformation) in the presence of a fluid phase and will be investigated in a wide range of minerals and rocks, under a range of chemical and physical conditions, using both natural and experimental samples. The principles of interface-coupled dissolution-reprecipitation will be applied to investigate the mechanisms of processes important in earth sciences and in industry, including metasomatic reactions in rocks, chemical weathering, mechanisms in CO2 sequestration, the aqueous durability of nuclear waste materials, remediation of contaminated water by mineral reaction, and the preservation of stone-based cultural heritage. The research methods bring together a range of complementary expertise, from field-related studies to nano-scale investigations of reaction interfaces using state-of-the-art high resolution analytical methods. The application of fundamental principles of mineral reequilibration to a wide range of applications, together with industrial involvement at all levels will ensure that the project provides a strong platform for training.
