Comments on applied magnetics in mineral exploration

Abstract

The subject of applied magnetics in hard rock environments has interested me for many years. Magnetic data are cheap and are employed by geophysicists and geologists in a variety of investigations including ore search, regional studies and lithological/structural elucidation. Most earth scientists, even academics, are familiar with magnetics. On reviewing the literature and perusing open file exploration company reports, one cannot help being struck by the imbalance between methodology and interpretation.
