context_page_description: Forbach Granite, also called Raumünzach-Granite, is a type of granite rock that occurs in the Northern Black Forest. It is part of the Northern Black Forest's granitic massif, to which Bühlertal granite and Wildbad granite also belong. Forbach granite predominantly outcrops in the counties of Calw and Rastatt. The most important quarrying area for Forbach granite used to be the middle Murg valley near Forbach. Today it is only quarried near Raumünzach.
  Forbach Granite is about 305 million years old. The stone is coarse-grained - this points to a slowly cooling of the lava / magma.
  Forbach Granite is a bright mica, coloured from gray to pink. Forbach Granite includes the following minerals.
  Alkali feldspars have a size of up to 5 centimetre and leads to a red colour.
  Quartz.
  Plagioclase
  Muscovite
  Biotite and leads to the distinct structured texture.
  Apatite
  Monazite
  Xenotime

  Forbach Granite is about 305 million years old. The stone is coarse-grained - this points to a slowly cooling of the lava / magma (at the time the formation of the stone).
  Forbach Granite is a bright mica, coloured from gray to pink. Forbach Granite includes the following minerals.
  Alkali feldspars (up to 44 percent) have a size of up to 5 centimetre and leads to a red colour.
  Quartz (26 percent).
  Plagioclase (20 percent)
  Muscovite (5 percent)
  Biotite (5 percent) and leads to the distinct structured texture.
  Apatite (below 1 percent)
  Monazite(rare)
  Xenotime (rare)
