- •
Biotite inclusions in quartz and feldspar are used to trace the origin of granitic magmas.
- •
Matrix and inclusion biotites in two-mica granite show consistent compositions with those from typical S-type granite.
- •
Inclusions biotites in biotite granite show a compositional transition between typical S- and I-type granites.
- •
The biotite inclusions in the biotite granite record the mixing between granitic magmas of different compositions.
