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.

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
