Field trip to locations of tin mineralization and alteration styles in the northwestern Bohemian Massif

Our SGA Student Chapter devoted its first field trip in 2012 to cassiterite mineralization and associated alteration in the northwestern part of the Bohemian Massif. We visited the Hieronymus mine at Čistá and the active quarry at Krásno.

The Čistá tin deposit:  the formation of postmagmatic greisens and late hydrothermal vein-type mineralization (Sn-W).

The active quarry at Krásno: open pit exploits alkali feldspar granites and alkali feldspathites as raw materials for ceramic, glass and chemical industry.
