Normative mineralogy calculation
WebThe recently opened Hera Au-Pb-Zn-Ag mine in central New South Wales has provided an ideal opportunity to demonstrate the calculation of sulfide ore mineralogy using … WebThis can be tedious. The second is using the CIPW Norm in which you take the Weight % of oxides in the rock, and using the Norm calculation it will tell you what minerals (and their amounts) you would expect to see in that rock. The normative calculation is a way to take an aphanitic or glassy volcanic rock (which lacks the crystalline ...

This is followed by a more detailed explanation of “slatenorm” and “slatecalculation” for low and very low metamorphic rocks, such as phyllites, slates, and shales. They are …
Webequilibrium mineralogy for any chemical composition at these conditions. However, the results of such a calculation might not be as useful as a CIPW norm for comparing the chemistries of different igneous rocks due to the variety of mineral compositions that would be found.

The CIPW Norm or Cation Norm is a useful tool for assessing silica saturation or oversaturation; estimations of minerals in a mathematical model are based on many assumptions and the results must be balanced with the observable mineralogy. The following areas create the most errors in calculations;
