a Schematics illustrating the Euler angle rotations of a calcite crystal used for assigning randomly oriented grain distribution in 3D. b Plots of relative overgrowth fraction (ROF) with growth step for the grain growth simulations in 2D and 3D. The dynamic behavior implies that overgrowth kinetics is faster in 2D as compared to 3D. c Simulated 2D calcite overgrowth (in rgb colors). Colorless white region in the domain denotes liquid. d Simulated 3D calcite cementation. The outlet pictures show the evolution of grains along the central plane of the 3D simulation. Appearance of additional grains from the adjacent planes is observed, which significantly influences the dynamics of evolution
