Rodney G. Downey,Denis R. Hirschfeldtal thin sections mounted on a glass slide backing, or alternatively as samples polished in a resin block. Microprobe techniques have, therefore, the ability to determine the composition of individual minerals in thin section or even concentration variations within a single grain.

The second unusual feature is that during neutron irradiation, they undergo nuclear fission, .U predominantly in a thermal neutron flux and .U, .Th in a fast neutron flux. These properties have led to the development of a number of techniques specific for uranium and thorium, including the following.
