Heß-Bruch (Heß'scher Bruch; Steinbruch Heß), Wurlitz, Oberkotzau, Münchberger Masse, Franken, Bayern, Deutschland

Serpentinite body with inclusions of saussurite gabbro, worked intermittently since around 1880. The material was initially used as a gravel for railway construction, because its low contents of sodium, potassium and calcium are largely prohibiting any plant growth. Later on, it was used as a filling material for synthetic polymers.
Located west of Wurlitz and about 5 km ESE of Oberkotzau.

Known for nice topazolite crystals.
