Fig. 8From: Elastic wave velocity and electrical conductivity in a brine-saturated rock and microstructure of poresThreshold for bond percolation as a function of coordination number. Threshold values for diamond, simple cubic, body-centered cubic (BCC) and face-centered cubic (FCC) lattices are 0.388, 0.2488, 0.1803 and 0.119, respectively (Stauffer and Aharony 1994)Back to article page
