SCOPE |
On the Earth’s surface
environments, the crystallization of minerals from multi-component aqueous
solutions implies in most cases the formation of solid solutions with more or
less wide compositional ranges, which are a record of the chemical environment
during crystallization. Moreover, the
interaction between existing minerals and water frequently leads to surface
precipitation and dissolution-recrystallization
processes, in which a number of substituting major, minor, or trace elements
redistribute to adapt to the new conditions. From an environmental point of
view, the study of ion partitioning between minerals and solutions can
provide very valuable information about natural waters, contamination of
soils and aquifers, and global element cycles. Ion partitioning is also
important in biomineralization, since the concentrations of specific minor and trace
elements in biogenic carbonates have been shown to correlate with various
parameters of the growth environment, including temperature, salinity,
nutrient levels, carbonate concentration, and water chemistry. All these topics will be considered in this school, which focuses on
ion partitioning from a multidisciplinary point of view: from the
thermodynamic fundamentals and geochemical modelling of mineral records to
the design of remediation strategies for contaminated waters, and the
development of climatic proxies. |
