ABSTRACT:
A sample of an earth formation is subjected to a magnetizing field. The magnetic and non-magnetic fractions of the earth formation sample are separated while under the influence of the magnetizing field. The weights of the magnetic and non-magnetic fractions are measured and the weight percentage of the magnetic fractions determined. The presence or absence of select minerals in the non-magnetic fraction is determined on the basis of the weight percentage of the magnetic fraction.
