Koenigsberger ratio
From HandWiki
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.[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. [math]\displaystyle{ Q = \frac{M_{rem}}{M_{ind}}= \frac{M_{rem}}{\chi H} }[/math][1]
| Definition | |
|---|---|
| Q | Königsberger Ratio |
| [math]\displaystyle{ M_{rem} }[/math] | remanent magnetization |
| [math]\displaystyle{ M_{ind} }[/math] | 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]
