Activate the logging of intermediate values in the console.
Check this box if you want the calculated norm to be normalized to 100%.
Enter desired ratio of Fe₂O₃ to FeO. The default value is "0" (see info):
Fe3+/(Total Iron) |
Total Fe as FeO |
If all iron in your rock occured as FeO, this is the weight-% of the rock this oxide would make up.
|
|
Desired Fe₂O₃ |
Weight-% Fe₂O₃ for the norm, based on your analysis, or on your requested ratio of Fe3+/(Total Iron), selected above.
|
|
Desired FeO |
Weight-% FeO for the norm, based on your analysis, or on your requested ratio of Fe3+/(Total Iron), selected above under "Correction Factors".
|
|
Weight corr. factor |
This value is used to recalculate your chemical analysis if you either decided to have the norm calculated to 100% total, or if you decided to change the ratio of the iron oxides in your analysis to use in the norm, or both.
