Fig. 4From: Structural analysis and susceptibility inversion based on ground magnetic data to map the chromite mineral resources: a case study of the Koh Safi Chromite Ore Deposit, Parwan, Afghanistana Total Magnetic Anomaly after diurnal correction, and b The total magnetic intensity after diurnal correction, IGRF subtraction, and reduction to pole. The total magnetic intensity refers to the overall strength of the magnetic field at a given point, whereas total magnetic anomaly concentrates on a deviation or fluctuation of the magnetic field from the value expectedBack to article page
