Abstract: Depth estimation of magnetic source bodies in parts of the Schist Belt of Kano, using Euler Deconvolution is presented in this paper. Detail ground magnetic survey was carried out using SCINTREX proton precession magnetometer to produce the Total Magnetic Intensity (TMI) map and consequently the residual map. The TMI ranges from 34,261 nT to 34,365 nT, while the residual field ranges from -160 nT to 115 nT. The depth estimate for contacts ranges from 6.5 m to 39.8 m, while that of dyke ranges from 8.9 m to 51.3 m. The depth estimation presented in this work is compared with the results of aeromagnetic study carried out in the same area and found to agree fairly well. Further, this also ensures the validity of aeromagnetic investigation in such applications. Keywords: Contacts, Dykes, Euler Deconvolution, Schist Belt. PACS: 91.25.F and 91.25.Rt.

Abstrak Telah dilakukan penelitian tentang Penentuan Struktur Bawah Permukaan Daerah GeothermalMenggunakan  Metode Geomagnet Dan Geolistrik Di Dusun Bahoan Kecamatan Silau Kahean Kabupaten Simalungun. Penelitian ini bertujuan untuk mengetahui kontur penyebaran fluida, penampang anomali dan model lapisan struktur bawah permukaan. Pengukuran metode geomagnet menggunakan PPM (Proton Precession Magnetometer) tipe Elsec 770, pengambilan data dilakukan secara acak dengan jumlah titik yang diperoleh 40 titik ukur, pengolahan data  menggunakan surfer 10 untuk mendapatkan peta kontur dan Mag2DCfor windows untuk mendapatkan penampang anomali magnetik. Metode geolistrik menggunakan alat Ares-G4 Versi 4,7 (Automatic Resistivity System) dan GPS (Global Position System) pengukuran metode geolistrik dilakukan dengan membentangkan elektroda serta menginjeksi arus melalui dua elektroda dan beda potensial yang muncul dapat terukur sehingga didapat harga resistivitas semu yang diperoleh dari alat geolistrik. Kemudian data diolah  menggunakanRes2Div untuk mendapatkan penampang kontur 2D dari nilai resistivitas lapisan batuan. Hasil penelitian menunjukkan bahwa kontur penyebaran fluida menggunakan metode geomagnet dan geolistrik tersebar secara vertikal, penampang anomali dengan metode geomagnet memiliki nilai terendah 22,75 nT dan nilai tertinggi 69,92 nT, dari penampang anomali didapat nilai suseptibilitas 0,00054, 0,0006, 0,0016 dimana model lapisan struktur bawah permukaan terdiri dari batuan pasir, lempung dan gamping. Untuk metode geolistrik memiliki nilai resistivitas (0,00-100)  dan model lapisan batuan lempung. Nilai resistivitas (150-200)  model lapisan batuan lanau. Nilai restivitas (350 – 500)  model lapisan pasir,  dan nilai restivitas >2250  model lapisan batu gamping.   Kata kunci: Geomagnet, Geolistrik, GPS, Suseptabilitas, Resistivity, Geothermal

The aeromagnetic method of geophysical surveying has been established in less than two decades as a powerful method in mining and petroleum exploration. Many economically important discoveries can either directly or indirectly be credited to the aeromagnetometer. Magnetic methods are most important in their assistance to geological reconnaissance and mapping. Also, deep crustal and upper‐mantle studies can be made from results. New instruments, the spin‐precession magnetometers, have come into being in the past five years. Included are the proton‐precession magnetometer, the alkali‐vapor rubidium and cesium instruments, and the metastable‐helium magnetometer. All of these devices have airborne capabilities, and their future use is destined to increase. Modern navigational and interpretational techniques have improved the usefulness of aeromagnetic surveying. Diurnal effects are corrected for and their behavior is becoming understood. Data compilation, the major step in the entire process between measurement and interpretation, is an involved routine, but can be automated with the aid of Doppler navigation and statistical techniques. Interpretative systems may be divided into qualitative inspection, profile analysis, and map methods. Numerous schemes have been proposed for analytic purposes and the principal methods are reviewed. Although much of the world has been covered by surveys, the program seems less than half done. With more emphasis on detailed surveys, comprehensive interpretation, and sensitive instruments, the future of aeromagnetics seems bright.
