Outcrop of thin sheets of phengite-rich marbles and dolomite marbles alternated with mica schists and schistose amphibolites in a gully of the March stream at an elevation of 2010 m, between the localities of Aebni or Äbni (indicated as Ebene on old Swiss maps) and Heinisch Stafel.

Red phengite and braunite are intimately intergrown in the fine-grained schistose marble. The mica-rich bands (1 to 3 cm) give the rock a conspicuous
reddish to pink and green striped appearence. The rock is composed of calcite, dolomite, phengite (red, yellowish, colourless and greenish), quartz, braunite, and hematite with additional garnet, biotite, rutile, and
zircon. Virtually mica-free bands alternate with mica-bearing bands. Red mica and greenish mica do not occur in the same bands. The yellowish micas associate, but are not intergrown with red mica. Small hematite flakes seem to be found within the yellow and red micas only. Small rutile and zircon crystals are optically observed in all mica types.
