Numerical unmixing of weakly and strongly magnetic

2019-1-6 · SUMMARY. The characterization of magnetic minerals in rocks often uses methods that measure induced magnetization. When rocks sediments or soils contain two magnetic phases in which one has a high saturation magnetization (M S) for example magnetite and the other a low M S for example hematite the induced magnetization will be dominated by the stronger phase.
