Abstract: In borehole ZK301 of a certain working area in Pingli of south Shaanxi,electrodes with a distance of approximately 100 m between every electrodes are arranged.On this basis,we perform the electrical logging and obtain some logging curves.Based on these curves in combination with the electrical parameters,we obtain that the two stages,at adepth of 112-137 m and 202-215 m,are the weakly mineralized zone,mainly caused by pyrite mineralization.However,at adepth of 225-245 m and 320-330 m,it becomes a strongly mineralized zone,mainly caused by the sphalerite.Because of the borehole,no other electrical logtest with different electrode distance has been performed.
