Liquidus Equilibria in the System K2O-Na2O-Al2O3-SiO2-F2O-1-H2O to 100 MPa: II. Differentiation Paths of Fluorosilicic Magmas in Hydrous Systems
Journal of Petrology
We investigated phase equilibria in the six-component system Na 2 O^K 2 O^Al 2 O 3^S iO 2^F2 O À1^H2 O at 100 MPa to characterize differentiation paths of natural fluorine-bearing granitic and rhyolitic magmas. Topaz and cryolite are stable saturating solid phases in calcium-poor systems. At 100 MPa the maximum solidus depression and fluorine solubility in evolving silicic melts are controlled by the eutectics haplogranite^cryolite^H 2 O at 6408C and $4 wt % F, and haplogranite^topaz^H 2 O atdoi:10.1093/petrology/egm002 fatcat:upr2ugjlhvgqtbjb5mesqmoq3a
