Abstract Most of the siliceous and carbonaceous concretions found in the black shales of the “Aalenian” of the Helvetic and Ultrahelvetic nappes in the Swiss Alps contain framboidal pyrite. Some framboids are assembled in polyframboids. The study of these framboids under reflected light and by electronic microanalyzer shows that they are constituted solely of pyrite. These framboids are described and further explanation of their genesis is presented.
