Effect of Pore-Scale Mineral Spatial Heterogeneity on Chemically Induced Alterations of Fractured Rock: A Lattice Boltzmann Study

Figure 3

The geometry of a single fracture (in light gray) surrounded by reactive (in black) and nonreactive (in dark gray) minerals. In multispecies simulations, dark gray is kaolinite and black is calcite. The QSGS algorithm was used to grow nonreactive minerals inside a reactive mineral (in black) to form a banded structure.
