CIPW norm calculation tool. An Average Crust analysis is preloaded. You can see its CIPW norm by pressing the 'Calculate Now' button.

To calculate a CIPW norm for you own anaysis, enter weight percents of the oxides in the appropriate input boxes and click the 'Calculate Now' button. Or upload chemical analyses from a Comma Separated Value (.csv) file by clicking on the "Choose File" button. The .csv file must must have the element oxide names in the first row as described in these instructions:

Select a Sample ID from the pulldown list that appears and click the 'Calculate Now' button. Only the first 20 analyses will be on the pulldown list.

Use the sliders to change the weight percent values for the oxides to see how the relative oxide proportions affect the normative mineralogy. For analyses that have all iron as FeO or as Fe2O3, a value can be entered for Fe+3/(Fe+2 + Fe+3). There are buttons to click that show the norm is oxygen units, rather than mass units, and to normalize the analysis to 100%
