Fig. 5From: Elastic wave velocity and electrical conductivity in a brine-saturated rock and microstructure of poresa, b Radial cross-sectional images of X-ray CT of a cylindrical sample (D = 2 mm, L = 6 mm). Cross sections are parallel to ZX-plane of a cylindrical sample AJG02. Lots of cracks (arrows) and round pores (rp) are imaged, and there many intragrain cracks in plagioclase grains. c An SEM image of ion-milled surface of AJG02Back to article page
