Koenigsberger ratio explained

The Koenigsberger ratio is the proportion of remanent magnetization relative to induced magnetization in natural rocks.^[1] It was first described by .^[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.

Q = (M _{rem})/(M _{ind}) = (M _{rem})/(\chi H)

Definition
	Koenigsberger ratio
M _{rem}	remanent magnetization
M _{ind}	induced magnetization
	the magnetic susceptibility; the influence of an applied magnetic field on a material
	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]
