Using this app, Streckeisen diagrams can now be created directly without having to calculate the CIPW norm first. Your QAPF data will be automatically normalized to 100 and you can directly download the diagram as a png file.
My sample is a ...
Q |
The quartz content in wt% of the norm. |
A |
The orthoclase content in wt% of the norm. |
P |
The plagioclase (albite and anorthite) content in wt% of the norm. |
F |
The content of nepheline and leucite in wt% of the norm. |
