WebAug 10, 2011 · Various physical properties including dry and wet density, saturated water content, specific gravity, and porosity, were determined for quartz mica schist in general accordance with ISRM (1972). The mean values obtained by averaging more than ten measurements for each property are presented in Table 2. Table 2. WebMar 22, 2024 · The experimental study on the electrical conductivities of schists with various contents of alkali ions (CA = K2O + Na2O = 3.94, 5.17, and 5.78 wt.%) were performed at high temperatures (623–1073 K) and high pressures (0.5–2.5 GPa). Experimental results indicated that the conductivities of schist markedly increased with the rise of …
