The solubility of potassium-feldspar in calcic plagioclase : experimental study and application to natural occurrences

Unusual feldspar intergrowths were found in two metamorphosed basalt dykes from Departure Rocks, Antarctica. They are composed of host calcic plagioclase (Kf 0 _3 An7 5_9 1 Ab9_25) and potassium-rich alkali feldspar (Kf90 _96 Ano_5 Ab0_8) lamellae. Their bulk composition is estimated to be Kf An 21...
