Basic Principles of the Calculation,um conditions. For this purpose, analytical data of the rock-forming minerals and for host rocks were statistically evaluated. The composition of a constituent, say clino-pyroxene, found to be characteristic of a certain rock type, was used in the calculation of the stable mineral assemblage of that particular rock.

In this system the result of the rock analysis is converted to a standard set of normative compounds using a fixed calculation scheme.

These average compositions of the constituent minerals are, of course, not constant throughout all rocks but vary with the rock type. This variation, in other words the relationship between the chemical composition of the magma

Comparison of the C.I.P.W. Norm with the Rittmann Norm,g to a fixed scheme. Most of these idealized minerals do not correspond to the natural rock-forming minerals, the composition of which is much more complicated. In order to illustrate this fact, the chemical compositions of some femic silicates are presented in Tables 1 and 2 in the form of their C.
