Three-dimensional reconstructions of clay fabric open a new dimension to fluid flow dynamic modeling. The tortuosity of pore pathways (ratio of shortest tortuous path to a straight line point-to-point) is an important property of flow dynamics at the clay nano- and microscales. Transmission electron micrographs and image analysis software were used to create 3D images of model (laboratory consolidated) and natural (polychaete fecal pellet) marine clay sediment for analyzing pore network properties. Our 3D renderings were segmented into 300 nm subsample cubes, orientation and volume measurements were made, and short pathways were identified. Flow pathway spread sheet maps were...
