Magnetic survey of the Savage River and Long Plains iron deposits, northwest Tasmania

This Bulletin describes magnetic surveys of the Savage River and Long Plains iron deposits in northwest Tasmania made by the Bureau of Mineral Resources, Geology and Geophysics between 1957 and 1962. The results of the surveys are shown as vertical magnetic field contours. The Bulletin includes a discussion of the theoretical magnetic anomaly due to an infinitely long dipping vein of infinite depth extent, and gives an interpretation for the magnetic anomalies observed on a selection of traverses. The drilling completed at Savage River and Long Plains as at May 1964 is summarised and compared with magnetic profiles. Recommendations for additional drilling are made, particularly in areas where drilling has not been done.
