ALGOL Program for the Computation of the Rittmann Norm

Part of the Minerals, Rocks and Inorganic Materials book series (MINERALS, volume 7)


The manual computation of the Rittmann norms is rather time-consuming; the whole algorithm was therefore programmed for electronic computers. The purpose of this program is the computation of the normative mineral association of a volcanic or plutonic rock on the basis of the Rittmann norms and the output of these results.
