“…As an illustrative example, we focus on spatial distributions of rates across the surface of a single calcite crystal subject to dissolution. Calcite is selected as an exemplary mineral because of its significance in environmental contexts as part of the carbon cycle (Bouissonnié et al., 2018) and as a key potential sink for toxic compounds such as Arsenic (Renard et al., 2019), Selenium (Heberling et al., 2014), Cadmium (Chada et al., 2005; Julia et al., 2023), Lead (Chada et al., 2005), Antimony (Renard et al., 2018), and Chromium (Guren et al., 2020). We induce the dissolution reaction at far‐from‐equilibrium conditions, that is, the solution is highly undersaturated with respect to calcium.…”

Chemical weathering associated with dissolution/precipitation at interfaces between minerals and flowing fluids is key for the evolution of geologic systems, including groundwater contamination and storage capacity. Relying on Atomic Force Microscopy (AFM) yields reaction rates at nanoscale resolutions. Challenges limiting our ability to quantify heterogeneity associated with these processes include establishing reliable platforms allowing AFM imaging of real‐time and in situ absolute material fluxes across mineral surfaces under continuous flow conditions to complement typically acquired surface topography images. We provide an experimental workflow and heterogeneous absolute rates at the nanoscale across the surface of a calcite crystal under dissolution. These high‐quality experimental observations are then interpreted through a stochastic approach. The latter is geared to embed diverse kinetic modes driving the degree of spatial heterogeneity of the reaction and corresponding to different mechanistic processes documented across the crystal surface.

“…Mineral precipitation can significantly influence the behavior of contaminants in the environment by altering their solubility and mobility, thereby affecting their transport and fate. The sequestration of inorganic pollutants (such as arsenic, antimony, selenium, and other heavy and toxic metals) in carbonates − and retention of radium by its coprecipitation with barium sulfate to treat contaminated water, water waste, and industrial waste − are only a few examples. Mineral precipitation in porous rocks plays a vital role in addressing several geo-energy challenges, such as scale formation in geothermal systems, injectivity impairment due to salt aggregates during CO 2 storage, ,, and clogging of reservoir rocks during enhanced hydrocarbon recovery.…”

Porous materials in natural and engineered environments are subject to morphological changes resulting from interacting chemical and physical processes. The intricate nature of these coupled processes, occurring at various temporal and spatial scales, poses challenges in predicting alterations in porosity and permeability. Delineating the controls of mineral precipitation reactions is particularly challenging because it requires the implementation of nucleation criteria and growth mechanisms. By conducting pore-scale simulations, we investigated the impact of the amount and stochastic distribution of crystallites, controlled by nucleation, on pore geometry and permeability in two-dimensional porous structures. The observed relationships between porosity and permeability exhibit characteristics that differ from the ones that are typically applied in dissolving porous media because of the clogging effect. Additionally, we propose a stochastic framework that upscales the coevolution of permeability and porosity across length scales. This framework enables the upscaling of clogging behavior to continuum-scale simulations based on statistical probability distributions of permeability–porosity variations.

Porous materials in natural and engineered environments are subject to morphological changes resulting from interacting chemical and physical processes. The complexity of coupled flow, transport, and chemical processes that occur on different temporal and spatial scales makes it difficult to predict the resulting porosity and permeability alterations. Delineating the controls of mineral precipitation reactions is particularly challenging because it requires the implementation of nucleation criteria and precipitation attributes. By conducting pore-scale simulations, we studied how the amount and stochastic distribution of crystallites, controlled by nucleation, affect the pore geometry and permeability in two-dimensional porous structures. The observed relationships between porosity and permeability show characteristics that differ from ones that are typically applicable in dissolving porous media because of the clogging effect. Additionally, we propose a stochastic framework that upscales the co-evolution of permeability and porosity across length scales. This framework enables precise communication of clogging behavior to continuum-scale simulations based on statistical probability distributions of permeability-porosity variations.
