Abstract (in english)
   The fulgurite studied originated by a lightning stroke during the thunderstorm observed at bedřichov near Liberec on August 24th, 2001. It forms small circular crater-like filled with pieces of a yellow greenish glass. The glass is mostly massive; rarely encountered drops some 15 mm across has attached elongated needle-shaped protrusions up to 10 mm long. The massive fulgurite contains lechatelierite and is heterogeneous with a bubble-rich fluidal structure; the only crystalline phase observed is quartz. The fulgurite drops are more homogeneous and also contain lechatelierite. chemical variation of fulgurite correpsonds to the source material - a soil overlying eathered biotite granite strongly modified by fractional vaporization. Heterogeneous source material containing abundant OH-bearing minerals probably influenced the shape of fulgurite, which is a circular crater-like depression instead of more common tube-like feature
