Experimental Measurement of the Transport Flow Path Aperture in Thermally Cracked Granite and the Relationship between Pore Structure and Permeability

Figure 13

Schematic illustration of variations in flow path geometry. Blue bold line: flow paths that are open to both the upper and lower ends of the sample (transport flow path); blue thin line: flow paths that are connected to the transport flow path but come to a dead-end or are isolated.
