Abstract

The magnetization of rocks is made up of an induced part, dependent on the ambient magnetic fielda remanent part that is a function of the history of the rock. Induced magnetization is parallel to the ambient magnetic field and its strength is proportional to that of the field and a single constant, the susceptibility. Remanent magnetization is a property of magnetic hysteresis and may be acquired under several different processes, separately or in combination. The most important physical property, as regards remanent magnetization, is that of magnetic coercivity expressed as the strength of a magnetic field required to change a remanent magnetization. Because rocks possess a spectrum of coercivities they often contain both “hard” and “soft” remanent magnetizations; moreover, the relative importance of the different magnetizations, including the induced magnetization, varies greatly from rock to rock.
