Evolution of magmatic AFM mineral assemblages in granitoid rocks; the hornblende + melt = biotite reaction in the Liberty Hill Pluton, South Carolina

The Liberty Hill pluton comprises a central, coarse-grained edenite + biotite granitic facies grading to a biotite, pargasite + biotite, or muscovite + biotite granitic marginal facies. The replacement of amphibole by biotite, mineral compositions and 'liquid' variation diagrams for the Li...

Beschreibung
Zusammenfassung:	The Liberty Hill pluton comprises a central, coarse-grained edenite + biotite granitic facies grading to a biotite, pargasite + biotite, or muscovite + biotite granitic marginal facies. The replacement of amphibole by biotite, mineral compositions and 'liquid' variation diagrams for the Liberty Hill help to determine the AFM mineral-crystallization reactions in the Liberty Hill pluton.
