Koenigsberger ratio

From Wikipedia, the free encyclopedia

The Koenigsberger ratio is the proportion of remanent magnetization relative to induced magnetization in natural rocks.[1] It was first described by J.G. Koenigsberger [de].[2] It is a dimensionless parameter often used in geophysical exploration to describe the magnetic characteristics of a geological body for help in interpreting magnetic anomaly patterns.

Definition
Q Koenigsberger ratio
remanent magnetization
induced magnetization
χ the magnetic susceptibility; the influence of an applied magnetic field on a material
H the macroscopic magnetic field

The total magnetization of a rock is the sum of its natural remanent magnetization and the magnetization induced by the ambient geomagnetic field. Thus, a Koenigsberger ratio, Q, greater than 1 indicates that the remanence properties contribute the majority of the total magnetization of the rock.[3]
