In this work, the transport of dense colloids through a water-saturated, bifurcating fracture is investigated using a constant spatial stepparticle tracking technique. The size of the constituents of a colloid plume is an important factor affecting the partitioning of dense colloidsat the bifurcation. While neutrally buoyant colloids partition between daughter fractures in proportion to flow rates, dense colloids willpreferentially exit fractures that are gravitationally downgradient, notwithstanding that the majority of the interstitial fluid may flow throughthe upper fracture. Comparison of the partitioning ratio between daughter fractures with the ratios of characteristic settling, diffusion, andadvection time reveal that these parameters control how colloids behave at fracture bifurcations.
