Abstract

ABSTRACT

This article deals with the effect that the Königsberger ratio, the ratio of remanent to induced magnetization, has in modifying the dipping‐dyke equation. Many reversed dykes are found on aeromagnetic maps and their presence indicates that remanent magnetism must often play a significant part in the magnetic expression of normally‐polarized dykes. The methods for the measurement of remanent magnetization and susceptibility () are outlined, and the relationship between and volume % magnetite () is discussed. It is proposed that a good approximation is = 0.15 (), where =1‐/100. The general equation for the dipping dyke, which includes the contribution of remanent magnetization, is given. A method of obtaining from the magnetic map is also derived.
