The method used to get subsurface information based on characteristic of their electricity.
2 one of geophysics method which can detect it is geoelectric especially induced polarization (IP). 1 Gold was associated with another mineral such as silver, copper, mercury or other element that affect by their circumstance. It has shaped as vein or dissemination in rock. Gold deposit was created by hydrothermal activity. Keywords: induced polarization, gold deposit, anomaly, resistivity, double dipole configuration Abbreviations We have chosen 2 lines TG.000 and TG.-200 that interest zone representing outcrops and induction polarization anomaly. Materials and tools that used were liquid CuSO 4, NaCl, 1 set Transmitter Phoenix model IPT1, 1 unit Receiver Phoenix model IPV1, 4 rolls of cables, 2 porous pot, 2 metal electrode, 1 unit power set with maximum output frequency 50 Hz, 2 units handy talky, 1 unit Laptop, software Microsoft excel 2007, software Surfer 9.0, and software Res2Dinv. Space between lines is 100 meters and space between electrodes is 50 meters. Induced polarization was measured by double dipole configuration as long as 2x1 kilometers. It used characteristic of polarization in medium when current was injected. One of geophysics method which suitable for metal mineral exploration is induced polarization method. It shaped as vein or dissemination of rock. Area TG was spotted as gold mineralization zone in Banyumas, Indonesia.
