Using the resistivity curve versus temperature developed for two granite bodies in Japan , we can roughly estimate the temperature of the granite in our area where its mean resistivity is 1000 m in the upper 5 km depth to be around 130◦C. Although the granite in our area is different in composition thanthe granite described , the estimated temperature value of 130◦C agrees well with temperatures of 122◦C and 127◦C calculated using the chalcedony and K-Mg geothermometers . In addition, the resistivity ofthe hot granite tends to decrease at depth of more than 5 km. Adecrease in resistivity may correspond to an increase in temperature as reported in many publications
