Field relationships and petrology of leucocratic schists from the Ravns Storø group near Fiskenæsset

Abstract

During field work in 1971-72 whilst mapping the Ravns Storø amphibolite belt (Andersen &amp; Friend, 1973) a series of leucocratic schists were found. These occur along the southceast side of the belt on the islands Íkátup nunâ, Sarqarigsup nunâ, Qagssikasaup nunâ and lkerasatsiaup nunâ. These rocks are initially striking because of their colour, paIe cream or yellowish, with the frequent development of spectacular garbenschiefer textures (Spry, 1969) in paIe brown, honey or colourless amphiboles (fig. 41).</jats:p
