Abstract
Penelitian menggunakan metode geofisika resistivitas dan polarisasi terimbas kawasan waktu (time domain) dengan maksud mengidentifikasi dan menginterpretasi litologi dan keberadaan mineral grafit berdasarkan respon nilai Resistivity dan Chargeability. Penelitian berlokasi di lapangan Tamboli, Kabupaten Kolaka, Sulawesi Tenggara. Pengambilan data lapangan menggunakan konfigurasi elektroda dipole – dipole dengan panjang lintasan pengukuran 200 m yang berjumlah 15 lintasan. Perangkat lunak yang digunakan adalah Ms. Excel, Res2Dinv, Rockwork, Surfer, dan Map Info 3D Discover. Hasil penelitian dan interpretasi terpadu dari beberapa lintasan, berdasar data anomali resistivitas daerah telitian tersusun oleh batuan metamorf yang terdiri dari batulempung dicirikan dengan nilai resistivitas >10 Ohm.m, batupasir dicirikan dengan nilai resistivitas 10-150 Ohm.m, batuan metasedimen dicirikan dengan nilai resistivitas 150-300 Ohm.m, Batuan Filit dicirikan dengan nilai resistivitas 300-500 Ohm.m, batuan sekis dicirikan dengan nilai resistivitas 500- 1000 Ohm.m, sekis kompak dicirikan dengan nilai resistivitas 1000-5000 Ohm.m, dan batuan Gneiss dicirikan dengan nilai resistivitas >5000 Ohm.m. Berdasarkan data anomali Chargeability penyebaran mineral grafit mengarah dari arah selatan ke arah utara yang ditandai dengan semakin banyaknya deposit mineral grafit yang semakin meningkat, daerah potensi mineralisasi ditandai dengan nilai Chargeability 100 - 400 m.sec. Dari pengolahan data sera interpretasi bawah permukaan maka disimpulkan bahwa daerah penelitian memiliki potensi adanya keberadaan mineral grafit yang sedikit. Mineral Grafit dijumpai berasosiasi dengan batuan metasedimen, filit, serta batuan sekis. Kata Kunci : Mineral Grafit, Metode Geolistrik, Polarisasi Terimbas, Time Domain, Resistivitas, Chargebilitas. The Research used geophysical resistivity and induced polarization time domain with the purpose of indicating and interpretation the mineralized zones of graphite based on the response value of resistivity and Chargeability. The Research is located on the Tamboli field, Kolaka, Southeast Sulawesi. Collection of field data used an electrode configuration dipole - dipole the measurement path length of 200 m from 15 tracks. The software used is Ms. Excel, RES2DINV, rockwork, Surfer, and 3D Map Info Discover. Results of the research and integrated interpretation of several trajectories based on data from the study area resistivity anomalies metamorphic rock composed of claystone is characterized by resistivity values> 10 Ohm.m, sandstone is characterized by resistivity values 10-150 Ohm.m, metasedimen rock characterized by resistivity values 150-300 Ohm.m, Rock filit characterized by resistivity values 300-500 Ohm.m, schist rocks are characterized by resistivity values Ohm.m 500-1000, compact schist characterized by resistivity values Ohm.m 1000-5000, and rock Gneiss is characterized by resistivity values> 5000 Ohm.m. Based on the Chargeability anomaly data the spread of mineral graphite leads from the south to the north which is marked by the increasing number of graphite mineral deposits increases, the potential areas of mineralization characterized by Chargeability values 100-400 m.sec. In this research the conclution is the study area has the potential for the presence of mineral graphite slightly. Mineral Graphite is found associated with rock metasedimen, filit, and schist rocks. Keywords: Mineral Graphite, Geolistrik method, Induced Polarization, Time Domain, resistivity, Chargeability.
