In the vicinity of mineralized granite cupolas at the Krupka (Graupen) ore district, there are both the kersantite dyke and intrusive breccia with lamprophyre fragments that were affected by greisenization process and enriched in tin (14-330 ppm Sn). heterogenous fluid flow is apparent in a millimetre to metre scale and mineralogical zoning is as follows: glimmeritic outer zone (+fluorite), topaz - mica - quartz inner zone adjacent to the cassiterite-quartz veinlets.
