STUDY OF METAL MINERALIZATION ZONE USING INDUCED POLARIZATION (IP) METHOD IN BALE VILLAGE TANANTOVEA DISTRICT DONGGALA

Abstract

ABSTRACT

Research to determine the distribution of metal mineralization zones have been conducted in the Balevillage, TanantoveaDistrict, Donggala regency using induced polarization time domain method with the dipole-dipole configuration. Measurements were made using geoelectrial supersting R8IP where measurements were conducted on 4 lines with electrode space of 4 meters. The data of induced polarization were processed using the software of Earthimager 2D. The interpretation is based chargeability and resistivity parameters supported by the regional geological information of the research area. Based on the result, can be concluded that the rocks structure beneath the surface of research area consists of fourprimary lithology units, namely sandstone, limestone, conglomerate rocks, and metamorphics rocks. Mineralization zone, which is quite rich in metals, lies in the sandstone layers with high chargeability of 50 ms - 150 ms, which is supported by the low resistivity in the range of 23 Ωm - 88 Ωm and anomalies appear West-East direction at the depth of ± 10 m - 44 m.
