Abstract

Eksplorasi bijih besi telah dilakukan di Bukit Munung Desa Sukabangun Kecamatan Sungai Betung Kabupaten Bengkayang. Tujuan penelitian ini adalah mengidentifikasi sebaran bijih besi di Bukit Munung baik secara lateral maupun vertikal. Penelitian ini menggunakan metode magnetik yang memanfaatkan parameter suseptibilitas batuan untuk menginterpretasikan struktur bawah bumi. Pengolahan data dilakukan dengan metode inversi untuk mendapatkan beberapa parameter fisis struktur bawah permukaan daerah yang ditinjau. Hasil pengamatan geologi dan pemetaan distribusi medan magnet menunjukkan potensi bijih besi berada di sebelah barat laut bukit. Berdasarkan distribusi nilai suseptibilitas batuan pada lintasan AB yang dibuat memotong daerah potensial tersebut, diduga bahwa terdapat tiga lokasi pengendapan batu besi berjenis hematit dan satu lokasi pengendapan batu besi berjenis hematit yang memiliki vein-vein magnetit.
