Data for Gravity Driven Chemical Dynamics in a Single Fracture

Fluid mixing and carbonate mineral distributions in fractures are controlled by gravity-driven chemical dynamics. Here, we provide images recorded during miscible reactive and non-reactive flow experiments in a uniform aperture fracture for different fracture inclination angles. A density contrast between two miscible fluids leads to the formation of a low-density fluid runlet whose width depends on the inclination angle and affects the extent of mixing and the distribution of precipitates.
