Abstract
Banyaknya kebutuhan akan bahan galian menyebabkan banyak dilakukannya kegiatan eksplorasi di Indonesia. Salah satu penelitian yang telah dilakukan ialah analisa penyebaran mineral sulfida menggunakan metode geolistrik induksi polarisasi didaerah Kabupaten Bombana, Sulawesi Tenggara. Metoda geolistrik adalah salah satu metoda geofisika untuk menyelidiki kondisi bawah permukaan, yaitu dengan mempelajari sifat aliran listrik pada batuan di bawah permukaan bumi. Metode induksi polarisasi merupakan salah satu metode geolistrik yang digunakan mendeteksi terjadinya polarisasi listrik pada permukaan mineral-mineral logam dengan mengamati efek polariasi akibat adanya induksi arus di bawah permukaan bumi. Teknik pengukuran yang digunakan ialah Time-Domain yang bertujuan untuk melihat perubahan beda potensial saat arus injeksi dimatikan. Mineral sulfida merupakan mineral hasil persenyawaan langsung antara unsur tertentu dengan sulfur Berdasarkan hasil penelitian bahwa mineral sulfida Kata Kunci : metode geolistrik, induksi polarisasi, dipole-dipole, time domain, resistivity, chargeability, mineral sulfida, batuan metasedimen, batuan metamorf. ABSTRACT IDENTIFICATION OF METAL SULFIDE MINERALS USING GEOELECTRICAL INDUCEED POLARIZATION AT “MJZ” FIELD, BOMBANA DISTRICT, SOUTH EAST SULAWESI By: Djoddy Mahardhika Z 115.110.033 The high demand for excavated materials cause many do exploration activities in Indonesia. One of the research that was do is the spread analysis of sulfide minerals using induced polarization geoelectric method, Bombana District, Southeast Sulawesi. Geoelectric method is one of geophysical methods to investigate subsurface conditions by learn the nature of electricity from rock in the subsurface. Method of induced polarization is one of the geoelectric method to detect the occurrence of polarization electric on the surface of metal minerals by observing the polarization effects due to induction currents in the subsurface earth. The measurement technique used is Time-Domain which aims to see the change in potential difference when the injection current is switched off. Mineral sulfide is a mineral of compound results between particular elements with sulfur Based on research results that the mineral sulfide Keywords: Geoelectric method, Induced polarization, Dipole-dipole, Time domain, Resistivity, Chargeability, Minerals sulphide, Metasedimentary rocks, metamorphic rocks.
