Abstract

During 1978 and 1979 the Bureau of Mineral Resources investigated the characteristics of the magnetic anomaly at Elura by a program of airborne, ground, carborne, and down-hole magnetic surveys, and laboratory magnetic measurements on core samples.

The results of this work show that the magnetic anomaly at Elura is caused mainly by a remanently magnetised pyrrho-titic zone within the Elura deposit. However, near-surface magnetic sources contribute to the anomaly at low altitudes.

Spectral analyses of airborne and carborne magnetic data at Elura indicate that the effects of near-surface and bedrock magnetic sources can be separated by careful attention to data acquisition and filtering.
