Fruchtschiefer is a local variety of contact metamorphic rock that is derived from argillite. == Formation and mineral content == Fruchtschiefer is formed under very low pressure (low grade metamorphic rock) and temperatures of ca. 500 °C. At these temperatures cordierite grows to the size of grains of corn, which is where its name comes from; ''Frucht'' being German for "corn" (as well as "fruit"). It contains the following minerals: cordierite, muscovite, potassium feldspar, quartz, biotite and hornblende.
