Crustal melting vs. fractionation of basaltic magmas: Part 1, granites and paradigms
Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

On ferroan (A-type) granitoids: their compositional variability and modes of origin
CD Frost, BR Frost - Journal of petrology, 2011 - academic.oup.com
We recognize eight types of ferroan granitoid that can be distinguished on the basis of major
element chemistry. These include alkalic granitoids that may be metaluminous or …

A geochemical classification for granitic rocks
This geochemical classification of granitic rocks is based upon three variables. These are
FeO/(FeO+ MgO)= Fe-number [or FeO tot/(FeO tot+ MgO)= Fe*], the modified alkali–lime …
