AB  - The results of electrical conductivity are often needed in studying the interior of the earth, which indirectly describes other physiochemical parameters of matter under high pressure and temperature. In this study, electrical conductivity and the temperature effects of some rock types have been measured, using ex-situ technique based on utilizing lee’s disc apparatus. Six rock types were studied, which are granite, rhyolite, shale, limestone, quartzite and marble. The mean electrical conductivity ranged from 0.183124&plusmn;0.02 S m <SUP>1</SUP> for Rhyolite to 0.259971&plusmn;0.03 S m <SUP>1</SUP> for limestone. Investigation shows that limestone has the highest electrical conductivity which increase as the air temperature increases while Rhyolite have the lowest electrical conductivity at all levels of temperature range.
