We address a vesicular basalt sample from Jabel Isbil Volcano that is located in Dhamar-Rada'a Volcanic Field (DRVF), SE Sana'a, Yemen. The studied vesicular basalt represents the main rock type at the top-hill volcano, whereas olivine basalt and mugearite represent the foot-hill and middle-hill volcano, respectively. Therefore, the present investigation stresses on vesicular basalt after thermal treatment processes. Our measurements revealed that the samples have semiconducting behavior with high electrical resistivity. Moreover, the dielectric constant has low/constant values. Electrical resistivity reached 1.2 G.ohm.m at room temperature. The authors strongly recommend that the vesicular basalts elsewhere give rise to high economic and strategic potential of high technologies.
