Quantitative predictions of natural and induced phenomena in fractured rock is one of the
great challenges in the Earth and Energy Sciences with far‐reaching economic and …

Abstract Models test our understanding of processes and can reach beyond the spatial and
temporal scales of measurements. Multi-component Reactive Transport Models (RTMs) …

Earth's climate may be stabilized over millennia by solubilization of atmospheric carbon
dioxide (CO2) as minerals weather, but the temperature sensitivity of this thermostat is …

The base of Earth's critical zone (CZ) is commonly shielded from study by many meters of
overlying rock and regolith. Though deep CZ processes may seem far removed from the …

A micro-continuum approach is proposed to simulate the dissolution of solid minerals at the
pore scale under single-phase flow conditions. The approach employs a Darcy–Brinkman …

In this paper, we discuss the recent kinetic work on water-rock interactions. Standard activity-
activity diagrams are reinterpreted, using a mass transfer kinetic model and recent data on …

The early hydration of alite, in particular the reason for the onset of the induction period, has
been a subject of controversy for many decades. Several theories have been proposed …

Abstract The Critical Zone (CZ) is the system of coupled chemical, biological, physical, and
geological processes operating together to support life at the Earth's surface. While our …

TOUGHREACT is a numerical simulation program for chemically reactive non-isothermal
flows of multiphase fluids in porous and fractured media. The program was written in Fortran …

This manuscript presents a benchmark problem for the simulation of single-phase flow,
reactive transport, and solid geometry evolution at the pore scale. The problem is organized …
