“…Interestingly, basalt has many excellent properties, such as resistance to corrosion, acidic and alkaline conditions, high pressure, and high temperature, which make it very useful (Bulut 2017;Wang et al 2017Wang et al , 2018. Basalt not only is used in buildings, railways, highways and other construction but also is an ideal raw material for producing "cast stone" (Bykov et al 1990; 1 3 Thorhallsson and Snaebjornsson 2016;Inman et al 2017;Gopinath et al 2017;Ma et al 2018). In addition, basalt is used as a high-quality fiber for high-temperature insulation, glassy fiber materials, fused glass for high wearing resistance pipes and natural floor tiles (Rapp et al 1985;Kapur et al 1995;TÖRe I and Ay 2004).…”

The electrical conductivity and wave velocity of basalt are important parameters for analyzing the evolution of the crust and mantle; they are also used in many fields, such as underground engineering. To analyze the influences of pressure and temperature on the electrical conductivity and wave velocity of basalt, this review summarizes many relevant references. The results show that mineralogical composition, microstructure, porosity, pressure and temperature have important influences on the conductivity and wave velocity of basalt. Electrical conductivity increases with temperature, while wave velocity tends to decrease with increasing temperature (especially above 400 °C) under low-pressure conditions (perhaps below 2 GPa). At high pressure (above 3 GPa), the wave velocity remains unchanged below 500 °C, while an abrupt increase occurs between approximately 500 and 850 °C, followed by a quick decrease above approximately 850 °C.
