IDENTIFIKASI ZONA MINERAL LOGAM DENGAN METODE INDUKSI POLARISASI ( IP ) DAERAH MEKARJAYA KECAMATAN CIDOLOG KABUPATEN SUKABUMI PROVINSI JAWA BARAT

Investigation has been done in the area of metal mineral zones Mekarjaya, District Cidolog, Sukabumi, West Java. The investigation was conducted by using Time Domain Induced Polarization geoelectric ( TDIP ) method Dipole-dipole configuration with the objective to determine the existence of metallic minerals, in the subsurface resistivity and chargeability values based on the rock. TDIP data retrieval done at thirteen tracks, electrode spacing 5 m and the path length 155 m and 235 m. The results of advanced data processing TDIP is true 2D resistivity and chargeability of each path. From the data resistivity, argillic alteration zones have low resistivity values between <50 Ωm - 100 Ωm, propylitic alteration zones have high resistivity value of 100 Ωm - 200 Ωm and silicified zones have a value indication resistivity> 200 Ωm. Chargeability data and the existence of metallic minerals that are in the zone of high ( > 100 msec ) . Based on the interpretation of 2D spread trending southwest-northeast of the study area.
