- Type
- Tin-tungsten greisens and stockworks
Historic district of Horní Slavkov (Schlaggenwald) and Krásno (Schönfeld), related to the Variscan granites of the Slavkovský les massif, mined since the Middle Ages. Cassiterite studied by Marahrens (2021) for Bronze Age tin provenance. Indicative coordinates.
