A preliminary magnetic survey on the iron-ore formation of Addatigala, Andhra Pradesh

  • A V S Murty


Three vertical magnetic profiles were run across an iron-ore formation near Addatigala. Theoretical fits have been obtained for the observed anomaly curves and the possible relation between the formation of the structure and eastern ghat tectonics is discussed. Laboratory determination of the susceptibility, remanence and coercivity of two samples from the structure have been made at various field strengths and the results are discussed.
