Notes on rock magnetization characteristics in applied geophysical studies

Abstract

The magnetic method is firmly established as an investigative procedure in applied geophysics, and it is increasingly recognised that an understanding of the elements of magnetic petrophysics assists in optimising field data interpretations. These notes expand on the rock magnetism data previously presented by Emerson (1979) and Clark (1983); the data presented are based on magnetic property studies in the CSIRO Division of Exploration Geoscience and the Department of Geology and Geophysics University of Sydney and on published studies and compilations. The systematic collection of petrophysical data by many workers over the last decade has greatly expanded the size and scope of available data.
