What is it about?
ILR is the only method that allows you to introduce geological constraints during the statistical elaboration of your data. As a result, you get a new type of map. One that shows the type of mineralization rather individual elements or their combination.

Why is it important?
This will help you not only reduce the number of maps but to better understand the ore potential of your target.
Perspectives
I hope that this will help to demystify the methods of compositional data analysis and to increase the quality of your future geochemical interpretation.
