Special Issue Information

Dear Colleagues,

All minerals and synthetic analogues, including new crystalline materials, grow, dissolve, and change their properties during alteration processes. In one way or another, decision makers in many different fields of all modern societies rely on accurate assessments of the rates of such processes as a function of environmental conditions. In a diverse range of important activities that include predictions of global climate change, drug development, steel corrosion, and nuclear waste management, crystal growth and dissolution kinetics will always be at the center of attention. Researchers in academic institutions, national research laboratories, and private industry are thus involved in precise quantification of the rates of mineral-fluid reactions, ultimately aimed at improving their fundamental understanding of underlying reaction kinetics. Even more challenging is the increasing need to correctly predict reaction rates.

This special volume on growth, dissolution and alteration kinetics of crystalline systems is devoted to providing a forum for the interested researcher to discuss areas that have seen significant advance, as well as those that are the center of controversy. Our aim is to capture research highlights, including a much needed, in-depth discussion of key theoretical concepts. Of special interest are contributions that address some of the most challenging topics, i.e., how do we up-scale our experimental and theoretical research results from the nano- to the macroscale?

Understanding mineral dissolution is relevant for natural and industrial processes that involve the interaction of crystalline solids and fluids. The dissolution of slow dissolving minerals is typically surface controlled as opposed to diffusion/transport controlled. At these conditions, the dissolution rate is no longer constant in time or space, an outcome observed in rate maps and correspondent rate spectra. The contribution and statistical prevalence of different dissolution mechanisms is not known. Aiming to contribute to close this gap, we present a statistical analysis of the variability of calcite dissolution rates at the nano- to micrometer scale. A calcite-cemented sandstone was used to perform flow experiments. Dissolution of the calcite-filled rock pores was measured using vertical scanning interferometry. The resultant types of surface morphologies influenced the outcome of dissolution. We provide a statistical description of these morphologies and show their temporal evolution as an alternative to the lack of rate spatial variability in rate constants. Crystal size impacts dissolution rates most probably due to the contribution of the crystal edges. We propose a new methodology to analyze the highest rates (tales of rate spectra) that represent the formation of deeper etch pits. These results have application to the parametrization and upscaling of geochemical kinetic models, the characterization of industrial solid materials and the fundamental understanding of crystal dissolution.
