Note on "birds-eye" textures in some Norwegian pyrrhotite-bearing ores.

Abstract

Three specimens, one from Råna, Nordland County, one from Lillefjellklumpen, Grong, Nord-Trøndelag County and one from Karmøy, Rogaland County, have been examined in polished sections. They all show the typical \"birds-eye\" textures in the pyrrhotite, a texture not previously reported in Norwegian pyrrhotite- bearing ores. The localities are plotted on the key map. fig. 1.
