Well imagine if we mapped granite, quartz, dolerite or adamellite boulders seperately?

Isn’t Adamellite just granite that is grey colour?

Its difficult to distinguish, just like trees can be "Adamellite - A term originally used for orthoclase-bearing tonalite of the Adamello Massif, but later used for granites with about equal amounts of alkali feldspar and plagioclase, which do not occur in the Adamello. The term should be avoided because of ambiguity and it is recommended that such rocks should be called monzogranite of QAPF field 3b"
