ABSTRACT. Potassium pargasite containing 3.19 wt. K20 was found in a skarn from the islet of Einst6dingen, L/itzow Holm Bay, East Antarctica, together with some high potassium pargasitic amphiboles. A positive correla-tion is shown between Fe2+/(Mg+Fe 2+) and K/(K+ Na(A)) ratios in pargasitic amphib...

Description
Summary:ABSTRACT. Potassium pargasite containing 3.19 wt. K20 was found in a skarn from the islet of Einst6dingen, L/itzow Holm Bay, East Antarctica, together with some high potassium pargasitic amphiboles. A positive correla-tion is shown between Fe2+/(Mg+Fe 2+) and K/(K+ Na(A)) ratios in pargasitic amphiboles suggesting that the increase of Fe 2 § serve to stabilize high-K pargasites under the metamorphic conditions of the granulite facies.
