Abstract

Telah dilakukan penelitian sebaran bijih besi di daerah Gurun Datar. Daerah ini merupakan daerah perbukitan yang dilewati oleh jalur sesar Sumatera. Metode yang digunakan adalah metode geomagnet. Berdasarkan pengolahan data diduga terdapat batuan hematit dengan nilai suseptibilitas antara 0,0100 s.d 0,0356 SI pada 29 titik dan urat mineral magnetit pada hematit dengan nilai suseptibilitas antara 0,0600 s.d 0,1753 SI di 5 titik. Nilai korelasi antara data obsevasi dan data kalkulasi berkisar 0,84 s.d 0,99.
